Dear all, I am using the gyrotropic module to compute the Berry curvature dipole D. Since w90 computes the *negative* Berry curvature when kslice_task=curv (or kpath_task=curv), and the D tensor is calculated from the Berry curvature, does the D tensor have a *negative* sign? Also, when the spin-orbit coupling is turned off, does it consider the spin degeneracy of the non-magnetic system? Or only one spin channel is considered? Thanks in advance,
Best regards, Sayantika Bhowal Postdoctoral fellow ETH, Zurich
