It is known that intrinsic currents in magnetic metals often appear in the direction
perpendicular to the external field for linear and nonlinear responses. Distinct from three …

In solid state systems, group representation theory is powerful in characterizing the behavior
of quasiparticles, notably the energy degeneracy. While conventional group theory is …

We show that interlayer charge transfer in 2D materials can be driven by an in-plane electric
field, giving rise to electrical multipole generation in linear and second order in-plane field …
