For a student encountering TFT for the first time, Le Bellac is the map through a dense mathematical forest.

Le Bellac provides a self-contained introduction to the two primary formalisms used to describe relativistic systems at finite temperature: Go to product viewer dialog for this item. thermal field theory le bellac pdf

While the Imaginary Time formalism is elegant for static properties (like the pressure or static correlation lengths), it is insufficient for studying transport phenomena or dynamic response. Le Bellac introduces the Real-Time Formalisms, specifically the Keldysh or Schwinger-Keldysh approach. For a student encountering TFT for the first
