Retarded versus time-nonlocal quantum kinetic equations — •K.

The finite duration of the collisions in Fermionic systems
as expressed by the retardation
time in the non-Markovian Levinson equation is discussed in the
quasiclassical limit.
We separate individual contributions included in the memory effect
resulting in (i) off-shell tails
of the Wigner distribution, (ii) renormalization of scattering rates
and (iii) of the single-particle energy, (iv) collision delay and (v)
related non-local corrections to the scattering integral. In this way
we transform the Levinson equation into the Landau-Silin equation
extended by the non-local corrections known from the theory of dense
gases.
The derived kinetic equation
unifies the Landau theory of quasiparticle transport with the
classical
kinetic theory of dense gases. The space-time symmetry is discussed
versus particle-hole symmetry and a solution is proposed which
transforms these two exclusive pictures into each other.
