Lorentz invariance vs. temperature in QFT
Abstract
The Lorentz invariance of a relativistic QFT is shown to be broken spontaneously at finite temperature with a zero-energy Goldstone spectrum which does not necessarily carry a one-particle structure. The Lorentz behaviour of the temperature is determined and the relation between Gibbs states in different Lorentz frames is clarified.
