Nonequilibrium Quantum Field Theory (Cambridge Monographs on Mathematical Physics)
"Nonequilibrium Quantum Field Theory by Calzetta and Hu is a very well written book which covers thoroughly various formalisms for studying  nonequilibrium statistical mechanics and nonequilibrium.quantum field theory.  It then uses these methodologies to address various important philosophical questions such as entropy generation, and quantum decoherence. Finally the authors show the relevance of these formalisms for addressing very current problems such as the dynamics of Bose-Einstein condensates, phase transitions following relativistic heavy ion collisions and nonequilibrium quantum processes in the time evolution of the early universe. The authors have written many of the seminal papers and the book is a masterpiece of pedagogy, explaining and resolving very clearly many of the technical issues that had to be overcome in the development of this subject. It should prove essential reading to anyone venturing to work in this important new field."Fred Cooper, Program Director Theoretical Physics, National Science Foundation"A valuable reference for graduate students and researchers in particle physics, gravitation, cosmology, atomic optical and condensed matter physics."Book News"This book is an exhaustive and up-to-date treatment of non-equilibrium quantum field theory, also considering its quite extensive lists of references. The coverage is excellent. The presentation is very detailed."Axel Maas, Mathematical Reviews
