• Gauge-invariant formulation of spin-current density-functional theory 

    Abedinpour, Saeed H.; Vignale, Giovanni, 1957-; Tokatly, I. V. (American Physical Society, 2010)
    Spin-currents and non-Abelian gauge potentials in electronic systems can be treated by spin-current density-functional theory, whose main input is the exchange-correlation (xc) energy expressed as a functional of spin-currents. ...
