Nonreciprocal phonon dichroism induced by Fermi pocket anisotropy in two-dimensional Dirac materials
Electrons in two-dimensional (2D) Dirac materials carry local band geometric quantities, such as the Berry curvature and orbital magnetic moments, which, combined with electron-phonon coupling, may affect the phonon dynamics in an unusual way. Here, we propose intrinsic nonreciprocal linear and circ...
