U(1)SU(2) Gauge Invariance Made Simple for Density Functional Approximations

S. Pittalis, G. Vignale, F. G. Eich

A semi-relativistic density-functional theory that includes spin-orbit couplings and Zeeman fields on equal footing with the electromagnetic potentials, is an appealing framework t…

Effective mass of quasiparticles from thermodynamics

F. G. Eich, Markus Holzmann, G. Vignale

We discuss the potential advantages of calculating the effective mass of quasiparticles in the interacting electron liquid from the low-temperature free energy vis-a-vis the conven…
