Ward identities and orbital magnetization in current density functional theory
Giovanni Vignale, Junren Shi, Di Xiao +1
We revisit the derivation of the orbital magnetization formula for periodic crystals in current density functional theory (CDFT)[1]. Our new derivation computes the linear response…
