Abstract
The time reversal symmetric polar phase of the spin-triplet superfluid 3He has two types of Dirac nodal lines. In addition to the Dirac loop in the spectrum of the fermionic Bogoliubov quasiparticles in the momentum space (px, py, pz), the spectrum of bosons (magnons) has Dirac loop in the 3D space of parameters—the components of magnetic field (Hx,Hy,Hz). The bosonic Dirac system lives on the border between the type-I and type-II.Description
