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,
