Perturbation and renormalization in thermo field dynamics
Journal Article
·
· Ann. Phys. (N.Y.); (United States)
A systematic renormalization procedure used in the perturbative calculation of the real-time causal Green's functions at finite temperature is presented. The formalism of thermo field dynamics is employed throughout, permitting the use of Feynman diagram techniques. The renormalizability by means of the temperature-independent counterterms is proved.
