Stochastic interpretation of Kadanoff-Baym equations
Carsten Greiner, Stefan Leupold
We show that the nonperturbative transport equations, the so called `Kadanoff-Baym equations', within the non-equilibrium real time Green's function description can be be understoo…

Resummation of soft modes in the free energy of Phi^4 theory
Stefan Leupold
A new method is proposed for the calculation of the free energy of an N-component Phi^4 theory at finite temperature. The method combines a perturbative treatment of the hard modes…
