Kadanoff-Baym equations

Kadanoff-Baym equations for an electron gas

Relation to the center of mass and difference time, t and tau

Relation of g< to the electron (Wigner) distribution function

Additional information in the Green's functions

Thus, the Kadanoff-Baym equations yield the renormalized single-particle spectrum, fully selfconsistently. To see the corresponding spectral functions, click here
