Leontovich Relations in Thermal Field Theory [PDF]

The European Physical Journal C, 2000
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.

Perturbative Non-Equilibrium Thermal Field Theory [PDF]

Physical Review D, 2013
We present a new perturbative formulation of non-equilibrium thermal field theory, based upon non-homogeneous free propagators and time-dependent vertices.

Thermal Field Theory and Infinite Statistics [PDF]

Nuclear Physics B, 1992
We construct a quantum thermal field theory for scalar particles in the case of infinite statistics. The extension is provided by working out the Fock space realization of a "quantum algebra", and by identifying the hamiltonian as the energy operator. We

Thermal Renormalons in Scalar Field Theory [PDF]

Modern Physics Letters A, 1999
In the frame of the scalar theory $g \phi ^{4}$, we explore the occurrence of thermal renormalons, i. e. temperature dependent singularities in the Borel plane.

Frozen ghosts in thermal gauge field theory [PDF]

, 2009
We review an alternative formulation of gauge field theories at finite temperature where unphysical degrees of freedom of gauge fields and the Faddeev-Popov ghosts are kept at zero temperature.Comment: 6 ...

Nuclearity and Thermal States in Conformal Field Theory [PDF]

Communications in Mathematical Physics, 2006
We introduce a new type of spectral density condition, that we call L^2-nuclearity. One formulation concerns lowest weight unitary representations of SL(2,R) and turns out to be equivalent to the existence of characters.

INTRODUCTION TO THERMAL FIELD THEORY [PDF]

International Journal of Modern Physics A, 1993
This is a very basic introduction and short (and of course incomplete) overview of thermal field theory. In the first part, I introduce the thermal propagator at a very simple level and give the Feynman rules using the time-path contour method. In the second part, I give examples of these rules in scalar theory and discuss the origin of the thermal ...

Introduction to thermal field theory [PDF]

, 1997
Within the next few years experiments at RHIC and the LHC will seek to create in the laboratory a quark-gluon plasma, the phase of matter in which the Universe was initially created. It is believed that the plasma will survive long enough to reach thermal equilibrium.
