Thermal Quantum Field Theory and Perturbative Non-Equilibrium Dynamics by Peter MillingtonEnglish | PDF | 2013 | 215 Pages | ISBN : 3319011855 | 4.7 MB
The author develops a new perturbative formalism of non-equilibrium thermal quantum field theory for non-homogeneous backgrounds. As a result of this formulation, the author is able to show how so-called pinch singularities can be removed, without resorting to ad hoc prescriptions, or effective resummations of absorptive effects.
