Finite-Temperature Field Theory: Principles and Applications (Cambridge Monographs on Mathematical Physics)
"...a wonderfully compact book, filled with useful information and important references."Mathematical Reviews"Overall, this book contains an excellent beginner's introduction to thermal quantum field theory, which paves the way to more in-depth topics. This book is highly recommendable to anyone entering the field, and very useful to advanced students in general and to researchers in adjacent topics as well."Axel Maas, Mathematical Reviews
