Current response in extended systems as a geometric phase: Application to variational wavefunctions (Journal of the Physical Society of the Japan, 2012)The linear response theory for current is investigated in a variational context. Expressions are derived for the Drude and superfluid weights for general variational wavefunctions. The expression for the Drude weight ...
