Description:
Author(s): Philip B. Allen Götze and Wölfle (GW) [ Phys. Rev. B 6 , 1226 (1972) ] wrote the conductivity in terms of a memory function M ( ω ) as σ ( ω + i η ) = ( i n e 2 / m ) [ ω + M ( ω + i η ) ] − 1 , where M ( ω + i η ) = i / τ in the Drude limit. The analytic properties of − M ( ω + i η ) are the same as those of the self-energy Σ of a retarded Green's function. In the … [Phys. Rev. B 92, 054305] Published Wed Aug 12, 2015
