No source-free exchange-correlation magnetic fields in non-collinear spin-density functional theory

Ester Livshits, Roi Baer

The source-free condition, $\nabla \cdot {\mathbf{B}}_{xc}=0$, where ${\mathbf{B}}_{xc}$ is the exchange-correlation (xc) magnetic field in non-collinear spin-density functional theory,…
