Abstract:A b s t r a c tVirial corrections to the Boltzmann equation for quasiparticles are obtained from non-equilibrium Green's functions. These corrections are expressed in terms of shifts in space and time that characterize non-locality of scattering integrals. The space shifts parallel finite-diameter corrections to collisions of hard spheres. The time shift is identified as the collision delay. All shifts are given by derivatives of the phase shift in a binary collision.
