The book "Thermal Field Theory" by Michel Le Bellac provides a thorough introduction to the subject, starting from the basics of quantum field theory and statistical mechanics. The author presents the material in a clear and concise manner, making it accessible to graduate students and researchers alike. The book covers a wide range of topics, including: The author presents the material in a clear
When using the PDF, keep a printed copy of Chapter 2’s Feynman rules and Appendix A (summaries of thermal propagators) at your desk. They will save hours of flipping pages. This is neither a hand-wavy introduction nor a
This is neither a hand-wavy introduction nor a pure mathematics monograph. Le Bellac assumes you have a working knowledge of standard QFT (at the level of Peskin & Schroeder, Chapter 1-10). From there, he builds the finite-temperature machinery gently.
) as a periodic imaginary time, the partition function can be calculated using path integrals. This leads to the , which are discrete energy sums used to evaluate thermal propagators.
