Exchange-correlation vector potentials and vorticity-dependent exchange-correlation energy densities in two-dimensional systems
arXiv:cond-mat/0308269 · doi:10.1103/PhysRevB.69.155302
Abstract
We present a new approach how to calculate the scalar exchange-correlation potentials and the vector exchange-correlation potentials from current-carrying ground states of two-dimensional quantum dots. From these exchange-correlation potentials we derive exchange-correlation energy densities and examine their vorticity (or current) dependence. Compared with parameterizations of current-induced effects in literature we find an increased significance of corrections due to paramagnetic current densities.
