Coordinate scaling in time-dependent current density functional theory
arXiv:cond-mat/0502590 · doi:10.1103/PhysRevA.72.020502
Abstract
The coupling constant dependence is derived in time-dependent {\em current} density functional theory. The scaling relation can be used to check approximate functionals and in conjunction with the adiabatic connection formula to obtain the ground-state energy from the exchange-correlation kernel. The result for the uniform gas using the Vignale-Kohn approximation is deduced.
