Thermal Field Theory in Equilibrium

Thermal field theory has applications in many areas of physics and one of those is the early Universe. There is an excess of matter over antimatter in the present Universe. Unless this was an initial condition in the Big Bang Scenario, this baryon asymmetry must have been created during the evolution of the Universe. According to Sakarov’s three criteria for baryogenesis, the Universe must have...

Finite Volume Effects in Thermal Field Theory

We analyze the effect of a finite volume on the thermodynamic potentials of a relativistic quantum field theory defined on a hypertorus at vanishing chemical potential. Using the symmetries of the Euclidean partition function, we interpret the thermodynamic observables as the expectation value of the energy-momentum tensor in the same theory living on a β×L2 volume. In the case where the screen...

On Thermal Entropy in Quantum Field Theory

Standard entropy calculations in quantum field theory, when applied to a subsystem of definite volume, exhibit area-dependent UV divergences that make a thermodynamic interpretation troublesome. Such divergences cannot be reabsorbed by local counterterms although, with a rather unusual procedure, they can be subtracted from the final result. A key issue here is which set of quantum degrees of f...

Leontovich Relations in Thermal Field Theory

The application of generalized Kramers-Kronig relations, the so-called Leontovich relations, to thermal field theory is discussed. Medium effects contained in the full, thermal propagators can easily be taken into account by this method. As examples the collisional energy loss of a charged particle in a relativistic plasma and the radiation of energetic photons from a quark-gluon plasma are con...

Two problems in thermal field theory

Two problems in thermal field theory François Gelis Brookhaven National Laboratory, Nuclear Theory, Bldg 510A, Upton, NY-11973, USA Abstract. In this talk, I review recent progress made in two areas of thermal field theory. In particular, I discuss various approaches for the calculation of the quark gluon plasma thermodynamical properties, and the problem of its photon production rate.
