dc.description.abstract | Magnetic van der Waals materials have recently emerged as a realization of quantum magnetism in two dimensions. They host a variety of phases including ferromagnets, anti-ferromagnets, helimagnets, and quantum spin liquids. The 2D nature of these materials makes them versatile platforms for quantum engineering. In this thesis, we explore via theoretical techniques how different quantum engineering methods allow to design and reveal exotic phases of matter in magnetic van der Waals materials. In particular, we will present three schemes. The first scheme focuses on external engineering on a 2D magnet to promote and identify the quantum spin liquid phase. The second scheme focuses on designing helical electronic states and heavy fermions via proximity to 2D magnets. The third scheme focuses on the utilization of the coupling of quantum magnets to the environment to design non-Hermitian many-body topological phases of matter. Our results put forward magnetic van der Waals materials as a versatile platform for engineering exotic phases of matter. | en |
