DESCRIPTION:Abstract: Classical kinetic theory is a very successful tool t
 o understand the dynamics of many-body systems that display low degeneracy
  and low-to-moderate correlation degree. In particular\, the behavior of h
 igh-temperature plasmas is very well captured using classical kinetic theo
 ry\, for which the latter assumptions are particularly valid. However\, as
  the microscopic details of the interactions become more and more importan
 t\, as well as quantum degeneracy and/or correlations start to play a role
 \, the resulting equations loose their validity\, and ab initio quantum ap
 proaches are required. In this talk\, I will discuss recent results of the
  application of quantum kinetic theory to study the interactions between m
 atter and radiation in terms of Wigner functions. I will start by introduc
 ing the main features of kinetic theories (both classical and quantum)\, a
 nd analyze their validity. The case of a quantum plasma will be examined i
 n detail. Then\, as an application\, I will discuss photon condensation in
  plasmas and photon turbulence in cold atoms.
