Thermal Field Theory

open access: yes, 1996
Now in paperback, this text introduces the theoretical framework for describing the quark-gluon plasma, an important new state of matter. The first part of this book is a self-contained introduction to relativistic thermal field theory. Topics include the path integral approach, the real and the imaginary time formalisms, fermion fields and gauge ...

Rules for diagrams in thermal field theories

Physical Review D, 1994
Sets of rules are proposed that allow one to write down the amplitude associated with a diagram at temperature [ital T], once the energy running around each loop has been summed over, in the imaginary-time formalism. Alternative forms are given: one is based on tree diagrams, another one on possible intermediate states.

Field theory in Rindler frame and more on the correspondence with thermal field theory formalisms

open access: yesAnnals of Physics
Considering two accelerated observers with same acceleration in two timelike wedges of Rindler frame we calculate the Feynman-{\it like} propagators for a real scalar field in a thermal bath with respect to the Minkowski vacuum.

Thermal Aspects in Quantum Field Theory

Annales Henri Poincaré, 2003
Thermal (or “KMS”) states as well as ground states are characterized by analyticity properties in the (complexified) time variable. Such a characterization is applied to the quantum field theoretical systems on Minkowski, de Sitter and anti-de Sitter spacetimes.
