Retarded and advanced green's function

Webwhich is the usual retarded Green’s function from a Lorentzian spectral weight. Evaluating G(z) in the strip N <0 gives an expression which is analytic in that strip and which analogously corresponds to the advanced Green’s function. The full analytic Green’s function with periodically repeated branch cuts corresponds to gluing WebGreen’s functions. The interesting result is that we can characterize the deviation from equilibrium (e.g. dissipation in case of the electrical conductivity) in terms of fluctuations …
