    Finite-momentum Cooper pairing in proximitized altermagnets
    (Nature Publishing Group, 2024-12) Zhang, Song Bo; Hu, Lun Hui; Neupert, Titus; Department of Applied Physics; Quantum Dynamics; University of Science and Technology of China; Universitat Zurich
    Finite-momentum Cooper pairing is an unconventional form of superconductivity that is widely believed to require finite magnetization. Altermagnetism is an emerging magnetic phase with highly anisotropic spin-splitting of specific symmetries, but zero net magnetization. Here, we study Cooper pairing in metallic altermagnets connected to conventional s-wave superconductors. Remarkably, we find that the Cooper pairs induced in the altermagnets acquire a finite center-of-mass momentum, despite the zero net magnetization in the system. This anomalous Cooper-pair momentum strongly depends on the propagation direction and exhibits unusual symmetric patterns. Furthermore, it yields several unique features: (i) highly orientation-dependent oscillations in the order parameter, (ii) controllable 0-π transitions in the Josephson supercurrent, (iii) large-oblique-angle Cooper-pair transfer trajectories in junctions parallel with the direction where spin splitting vanishes, and (iv) distinct Fraunhofer patterns in junctions oriented along different directions. Finally, we discuss the implementation of our predictions in candidate materials such as RuO2 and KRu4O8.

    From intangible to tangible : The role of big data and machine learning in walkability studies
    (Elsevier Ltd, 2024-04) Yang, Jun; Fricker, Pia; Jung, Alexander; Department of Architecture; Department of Computer Science; Computer Science Professors; Computer Science - Large-scale Computing and Data Analysis (LSCA); Computer Science - Artificial Intelligence and Machine Learning (AIML); Helsinki Institute for Information Technology (HIIT); Professorship Jung Alexander
    Walkability reflects the well-being of a city, and its measurement is evolving rapidly due to advancements of big data and machine learning technologies. The study examines the transformative impact of these technological interventions on the evaluation of walkability trends over the period 2015 to 2022. We create a framework consisting of big data sources, machine learning methods, and research purposes, revealing research trajectories and associated challenges. Despite diverse data usage, image data dominates in walkability research. While street view and point of interest data were primarily used to depict the environment, social media and handheld/ wearable data were more commonly employed to represent user behaviours or perceptions. Leveraging machine learning in conjunction with big data assists researchers in three aspects of walkability studies. First, researchers utilise classification and clustering to predict street quality, walkability, and identify neighbourhoods with certain characteristics. Second, researchers unveil relationship between the built environment and pedestrian perceptions or behaviours through regression analysis. Third, researchers employ generative models to create streetscapes or urban structures, although their utilisation is limited. Meanwhile, challenges persist in data access, customisation of machine learning models for urban studies, and establishing standard criteria to guarantee data quality and model accuracy.

    A User-Centered Lens into Digital Excess : Exploring the Superfluity and Environmental Burden of the Digital World
    (2023-06-14) Olsson, Thomas; Pyyhtinen, Olli; Rantasila, Anna; Laaksonen, Salla-Maaria; Vigren, Minna; Ylipulli, Johanna; Sawhney, Nitin; Department of Computer Science; Lecturer Sarvas Risto; Computer Science Professors of Practice; Computer Science - Human-Computer Interaction and Design (HCID); Computer Science - Digital Ethics, Society and Policy (Digital-ESP); Professor of Practice Sawhney Nitin; Tampere University; University of Helsinki
    This article seeks to take a new view on the environmental burden of information and communication technology through the concept of digital excess. Our notion of digital excess draws from Georges Batailleʼs argument that the main problem of any economy is excess rather than scarcity. We take a user-centric lens into this concept and discuss various aspects of our digital lives that could be perceived not to carry meaningful value but appear as wasteful and superAluous, while also harming individuals, society, or the planet. We provide examples from digital media services where digital excess may be regarded as, for example, accumulation of self-created content with redundant copies or inattentive consumption of highbandwidth streaming services. In consonance with related work in the Sustainable Human-Computer Interaction community, we encourage follow-up empirical investigations of the practical manifestations of this concept, which could help to further understand, problematize, and possibly also mitigate the growing energy use of ICT. For the design of digital services, focusing on digital excess offers a lens through which designers could simultaneously optimize multiple quality criteria that conventionally require trade-offs (e.g., environmental sustainability vs. lively user experience vs. economic viability).

    Too Overloaded to Use : An Adaptive Network Model of Information Overload during Smartphone App Usage
    (2024-02-29) Bracy, Emerson; Lassila, Henrik; Treur, Jan; Department of Computer Science; Cherifi, Hocine; Rocha, Luis M.; Cherifi, Chantal; Donduran, Murat; Colby College; Vrije Universiteit Amsterdam
    In this paper, a first-order adaptive self-modeling network model is introduced to model information overload in the context of cyclical usage of smartphone apps. The model consists of interacting attention resources and emotional responses to both attention taxation and the app engagements. The model makes use of first-order reification to simulate the agent’s learning of the connections between app engagement and emotional responses, and strategic use of attention resources. Furthermore, external factors, such as context and influence of the environment to use the apps, are included to model the usage decision of the agent. Simulations in two scenarios illustrate that the model captures expected dynamics of the phenomenon.

    Compilation of algorithm-specific graph states for quantum circuits
    (Institute of Physics Publishing, 2024-04) Krishnan Vijayan, Madhav; Paler, Alexandru; Gavriel, Jason; Myers, Casey R.; Rohde, Peter P.; Devitt, Simon J.; Department of Computer Science; Computer Science - Quantum Software and Algorithms (QUANTUM); Professorship Paler Alexandru; Computer Science Professors; Computer Science - Algorithms and Theoretical Computer Science (TCS); University of Technology Sydney; University of Melbourne
    We present a quantum circuit compiler that prepares an algorithm-specific graph state from quantum circuits described in high level languages, such as Cirq and Q#. The computation can then be implemented using a series of non-Pauli measurements on this graph state. By compiling the graph state directly instead of starting with a standard lattice cluster state and preparing it over the course of the computation, we are able to better understand the resource costs involved and eliminate wasteful Pauli measurements on the actual quantum device. Access to this algorithm-specific graph state also allows for optimisation over locally equivalent graph states to implement the same quantum circuit. The compiler presented here finds ready application in measurement based quantum computing, NISQ devices and logical level compilation for fault tolerant implementations.

    Reciprocal Relations Between Meaning in Life, Beneficence, and Psychological Needs for Autonomy, Competence, and Relatedness : Evidence from a Three-Wave Longitudinal Study
    (Springer, 2024-03) Martela, Frank; Unanue, Jesús; Gómez, Marcos; Unanue, Wenceslao; Department of Industrial Engineering and Management; Universidad Andrés Bello; Universidad Adolfo Ibáñez
    Meaning in life has been established as a key factor of human well-being and flourishing. Beneficence and the three psychological needs of self-determination theory-autonomy, competence, and relatedness—have all been individually studied as antecedents of meaningfulness. Yet, no previous research has examined them neither longitudinally nor simultaneously as predictors of meaning over time. In a three-wave longitudinal study in Chile (n: T1 = 1477, T2 = 820, T3 = 487) we examined the reciprocal relations between autonomy, competence, relatedness, beneficence, and meaning, using cross-lagged panel analysis. Taken individually, each of the four factors predicted meaning, and when entered simultaneously into the same model, competence, relatedness, and beneficence predicted meaning over time. Furthermore, we found that meaning predicted all four factors over time. Our results thus advance research on meaning in life by examining key predictors of it and showing that meaning itself predicts the same factors dynamically over time.

    Hybridization of electromagnetic multipoles in a nanoscatterer in the presence of another nanoscatterer
    (Institute of Physics Publishing, 2024-02-01) Sehrawat, Sagar; Kolkowski, Radoslaw; Shevchenko, Andriy; Department of Applied Physics; Optics and Photonics; Optics and Photonics
    Coupling between multipolar modes of different orders has not been investigated in depth, despite its fundamental and practical relevance in the context of optical metamaterials and metasurfaces. Here, we use an electromagnetic multipole expansion of both the scattered fields and the oscillating electric currents to reveal the multipolar excitations in a nanoparticle positioned close to another nanoparticle. The considered single-particle multipoles radically differ from multipoles excited in a pair of nanoparticles. Using the expansion, we reveal the multipole character of the electric currents and the contributions of the multipole moments to the scattering cross section of each particle, including the effect of their interaction. We find that light scattered by the particles plays the role of an inhomogeneous incident field for each of the particles, leading to hybridization of the originally independent orthogonal multipole resonances. For an incident plane wave polarized along the nanoparticle pair, the hybridization of the dipole and quadrupole resonances gives rise to a significant narrowband resonance in the spectrum of the dipole scattering, which can be of interest for various applications, e.g. in surface-enhanced fluorescence and Raman spectroscopy. In general, this work shows that the multipole-multipole interaction between nanoparticles must be treated by taking into account also such hybridized multipole resonances.

    Parabolic John–Nirenberg spaces with time lag
    (Springer, 2024-03) Myyryläinen, Kim; Yang, Dachun; Department of Mathematics and Systems Analysis; Analysis; Beijing Normal University
    We introduce a parabolic version of the so-called John–Nirenberg space that is a generalization of functions of parabolic bounded mean oscillation. Parabolic John–Nirenberg inequalities, which give weak type estimates for the oscillation of a function, are shown in the setting of the parabolic geometry with a time lag. Our arguments are based on a parabolic Calderón–Zygmund decomposition and a good lambda estimate. Chaining arguments are applied to change the time lag in the parabolic John–Nirenberg inequality.

    Tailoring Hot-Carrier Distributions of Plasmonic Nanostructures through Surface Alloying
    (American Chemical Society, 2024-02-16) Fojt, Jakub; Rossi, Tuomas P.; Kumar, Priyank V.; Erhart, Paul; Department of Applied Physics; Computational Electronic Structure Theory; Chalmers University of Technology; University of New South Wales
    Alloyed metal nanoparticles are a promising platform for plasmonically enabled hot-carrier generation, which can be used to drive photochemical reactions. Although the non-plasmonic component in these systems has been investigated for its potential to enhance catalytic activity, its capacity to affect the photochemical process favorably has been underexplored by comparison. Here, we study the impact of surface alloy species and concentration on hot-carrier generation in Ag nanoparticles. By first-principles simulations, we photoexcite the localized surface plasmon, allow it to dephase, and calculate spatially and energetically resolved hot-carrier distributions. We show that the presence of non-noble species in the topmost surface layer drastically enhances hot-hole generation at the surface at the expense of hot-hole generation in the bulk, due to the additional d-type states that are introduced to the surface. The energy of the generated holes can be tuned by choice of the alloyant, with systematic trends across the d-band block. Already low surface alloy concentrations have a large impact, with a saturation of the enhancement effect typically close to 75% of a monolayer. Hot-electron generation at the surface is hindered slightly by alloying, but here a judicious choice of the alloy composition allows one to strike a balance between hot electrons and holes. Our work underscores the promise of utilizing multicomponent nanoparticles to achieve enhanced control over plasmonic catalysis and provides guidelines for how hot-carrier distributions can be tailored by designing the electronic structure of the surface through alloying.

    A Scalable, Incoherent-Light-Powered, Omnidirectional Self-Oscillator
    (Wiley-VCH Verlag, 2024-02) Nemati, Y; Deng, ZX; Pi, HT; Guo, HS; Zhang, H; Priimagi, A; Zeng, H; Department of Applied Physics; Molecular Materials; Tampere University; Molecular Materials
    Light-fueled self-oscillators based on stimuli-responsive soft materials have been explored toward the realization of a myriad of nonequilibrium robotic functions, such as adaptation, autonomous locomotion, and energy conversion. However, the high energy density and unidirectionality of the light field, together with the unscalable design of the existing demonstrations, hinder their further implementation. Herein, a light-responsive lampshade-like smart material assembly as a new self-oscillator model that is unfettered by the abovementioned challenges, is introduced. Liquid crystal elastomer with low phase transition temperature is used as the photomechanical component to provide twisting movement under low-intensity incoherent light field. A spiral lampshade frame ensures an equal amount of light being shadowed as negative feedback to sustain the oscillation upon constant light field from omnidirectional excitation (0°–360° azimuth and 20°–90° zenith). Different-sized oscillators with 6, 15, and 50 mm in diameter are fabricated to prove the possibility of scaling up and down the concept. The results provide a viewpoint on the fast-growing topic of self-oscillation in soft matter and new implications for self-sustained soft robots.

    Self-reported strategy use in working memory tasks
    (Nature Publishing Group, 2024-12) Ritakallio, Liisa; Fellman, Daniel; Salmi, Juha; Jylkkä, Jussi; Laine, Matti; Department of Neuroscience and Biomedical Engineering; Åbo Akademi University
    Mnemonic strategies can facilitate working memory performance, but our knowledge on strategy use as a function of task characteristics remains limited. We examined self-reported strategy use in several working memory tasks with pretest data from two large-scale online training experiments. A three-level measure of strategy sophistication (no strategy, maintenance, manipulation) was coded based on participants’ open-ended strategy reports. A considerable portion of participants reported some memory strategy, and strategy sophistication was associated with objective task performance. We found a consistent effect of stimulus type: verbal stimuli (letters or digits) elicited higher strategy sophistication than nonverbal ones (colours or spatial positions). In contrast, the association between task paradigm and strategy sophistication was less consistent in the two experiments. The present results highlight the importance of self-generated strategies in understanding individual differences in working memory performance and the role of stimulus characteristics as one of the task-related determinants of strategy use.

    Elucidation of protein-ligand interactions by multiple trajectory analysis methods
    (Royal Society of Chemistry, 2024-02-05) Wu, Nian; Zhang, Ruotian; Peng, Xingang; Fang, Lincan; Chen, Kai; Jestilä, Joakim S.; Department of Applied Physics; Surfaces and Interfaces at the Nanoscale; Tsinghua University; Zhejiang University
    The identification of interaction between protein and ligand including binding positions and strength plays a critical role in drug discovery. Molecular docking and molecular dynamics (MD) techniques have been widely applied to predict binding positions and binding affinity. However, there are few works that describe the systematic exploration of the MD trajectory evolution in this context, potentially leaving out important information. To address the problem, we build a framework, Moira (molecular dynamics trajectory analysis), which enables automating the whole process ranging from docking, MD simulations and various analyses as well as visualizations. We utilized Moira to analyze 400 MD simulations in terms of their geometric features (root mean square deviation and protein-ligand interaction profiler) and energetics (molecular mechanics Poisson-Boltzmann surface area) for these trajectories. Finally, we demonstrate the performance of different analysis techniques in distinguishing native poses among four poses.

    High-fidelity robust qubit control by phase-modulated pulses
    (American Physical Society, 2024-01) Kuzmanović, Marko; Björkman, Isak; McCord, John J.; Dogra, Shruti; Paraoanu, Gheorghe Sorin; Department of Applied Physics; Superconducting Qubits and Circuit QED; Centre of Excellence in Quantum Technology, QTF; Department of Applied Physics
    We present a set of robust and high-fidelity pulses that realize paradigmatic operations such as the transfer of the ground state population into the excited state and arbitrary X/Y rotations on the Bloch sphere. These pulses are based on the phase modulation of the control field. We provide an experimental proof-of-concept of these operations by using a transmon qubit, demonstrating resilience against deviations in the drive amplitude of more than ≈20%, and/or detuning from the qubit transition frequency in the order of 10MHz. This modulation scheme is straightforward to implement in practice and can be deployed to any other qubit-based experimental platform.

    In Vivo Toxicological Analysis of the ZnFe2O4@poly(tBGE-alt-PA) Nanocomposite : A Study on Fruit Fly
    (American Chemical Society, 2024-02-13) Chauhan, Shaily; Naik, Seekha; Kumar, Rohit; Ruokolainen, Janne; Kesari, Kavindra Kumar; Mishra, Monalisa; Gupta, Piyush Kumar; Department of Applied Physics; Molecular Materials; Sharda University; National Institute of Technology, Rourkela
    Recently, the use of hybrid nanomaterials (NMs)/nanocomposites has widely increased for the health, energy, and environment sectors due to their improved physicochemical properties and reduced aggregation behavior. However, prior to their use in such sectors, it is mandatory to study their toxicological behavior in detail. In the present study, a ZnFe2O4@poly(tBGE-alt-PA) nanocomposite is tested to study its toxicological effects on a fruit fly model. This nanocomposite was synthesized earlier by our group and physicochemically characterized using different techniques. In this study, various neurological, developmental, genotoxic, and morphological tests were carried out to investigate the toxic effects of nanocomposite on Drosophila melanogaster. As a result, an abnormal crawling speed of third instar larvae and a change in the climbing behavior of treated flies were observed, suggesting a neurological disorder in the fruit flies. DAPI and DCFH-DA dyes analyzed the abnormalities in the larva’s gut of fruit flies. Furthermore, the deformities were also seen in the wings and eyes of the treated flies. These obtained results suggested that the ZnFe2O4@poly(tBGE-alt-PA) nanocomposite is toxic to fruit flies. Moreover, this is essential to analyze the toxicity of this hybrid NM again in a rodent model in the future.

    From convective stellar dynamo simulations to Zeeman-Doppler images
    (EDP Sciences, 2024-02-01) Hackman, T.; Kochukhov, O.; Viviani, M.; Warnecke, J.; Korpi-Lagg, M. J.; Lehtinen, J. J.; Department of Computer Science; Computer Science Professors; Computer Science - Large-scale Computing and Data Analysis (LSCA); Professorship Korpi-Lagg Maarit; University of Helsinki; Uppsala University; Wish s.r.l; Max Planck Institute for Solar System Research; University of Turku
    Context. Zeeman-Doppler imaging (ZDI) is used to reconstruct the surface magnetic field of late-type stars from high-resolution spectropolarimetric observations. The results are usually described in terms of characteristics of the field topology, such as poloidality versus toroidality and axisymmetry versus non-axisymmetry, in addition to the field strength. Aims. In this study, we want to test how well these characteristics are preserved when applying the ZDI method to simulated data. We are particularly interested in how accurately the field topology is preserved and to what extent stellar parameters, such as projected rotation velocity and rotation axis inclination, influence the reconstruction. Methods. For these tests, we used published magnetic field vector data from direct numerical magnetohydrodynamic simulations taken near the surface of the simulation domain. These simulations have variable rotation rates and therefore represent different levels of activity of an otherwise Sun-like setup with a convective envelope of solar thickness. Our ZDI reconstruction is based on spherical harmonics expansion. By comparing the original values to those of the reconstructed images, we study the ability to reconstruct the surface magnetic field in terms of various characteristics of the field. Results. In general, the ZDI method works as expected. The main large-scale features are reasonably well recovered, but the strength of the recovered magnetic field is just a fraction of the original input. The quality of the reconstruction shows clear correlations with the data quality. Furthermore, there are some spurious dependencies between stellar parameters and the characteristics of the field. Conclusions. Our study uncovers some limits of ZDI. Firstly, the recovered field strength will generally be lower than the ‘real’ value, as smaller structures with opposite polarities will be blurred in the inversion. This is also seen in the relative distribution of magnetic energy in terms of the angular degree `. Secondly, the axisymmetry is overestimated. The poloidality versus toroidality is better recovered. The reconstruction works better for a stronger field and faster rotation velocity. Still, the ZDI method works surprisingly well even for a weaker field and slow rotation provided the data have a high signal-to-noise ratio and good rotation phase coverage.

    Beta- and gamma-band cortico-cortical interactions support naturalistic reading of continuous text
    (Wiley-Blackwell, 2024-01) Kujala, Jan; Mäkelä, Sasu; Ojala, Pauliina; Hyönä, Jukka; Salmelin, Riitta; Department of Neuroscience and Biomedical Engineering; Aalto University; University of Turku
    Large-scale integration of information across cortical structures, building on neural connectivity, has been proposed to be a key element in supporting human cognitive processing. In electrophysiological neuroimaging studies of reading, quantification of neural interactions has been limited to the level of isolated words or sentences due to artefacts induced by eye movements. Here, we combined magnetoencephalography recording with advanced artefact rejection tools to investigate both cortico-cortical coherence and directed neural interactions during naturalistic reading of full-page texts. Our results show that reading versus visual scanning of text was associated with wide-spread increases of cortico-cortical coherence in the beta and gamma bands. We further show that the reading task was linked to increased directed neural interactions compared to the scanning task across a sparse set of connections within a wide range of frequencies. Together, the results demonstrate that neural connectivity flexibly builds on different frequency bands to support continuous natural reading.

    Unfolding dispositifs : Attempts at digital business education in North Korea
    (SAGE Publications, 2024-02-26) Wainwright, Thomas; Kibler, Ewald; Scott, Will; Heikkilä, Jukka-Pekka; Department of Industrial Engineering and Management; Department of Management Studies; University of London; Protocol Labs
    Scholars have drawn attention to educational spaces as sites of contestation and struggle. Researchers have increasingly scrutinised the power structures and relations that shape educational spaces, particularly in the mobilisation of education to further the economic competitiveness of nation-states. Adopting a dispositif lens, our ethnographic study examines digital business education in a North Korean university. In doing so, we uncover the unstable interplay between a dispositif of paternalist care and a dispositif of discipline, which are both required by the regime to control the development of new digital capabilities, examining the techniques used to develop and restrict digital education. In conclusion, our paper develops new understanding of how digital capabilities, through education, are simultaneously enabled and constrained, and how dispositifs differentially unfold across space.
