Optimized Perturbation Theory at Finite Temperature --- Renormalization and Nambu-Goldstone theorem in O(N) phi^4 Theory ---
S. Chiku, T. Hatsuda
The optimized perturbation theory (OPT) at finite temperature recently developed by the present authors is reviewed by using O(N) phi^4 theory with spontaneous symmetry breaking. T…

Optimized Perturbation Theory at Finite Temperature
S. Chiku, T. Hatsuda
An optimized perturbation theory (OPT) at finite temperature T, which resums higher order terms in the naive perturbation, is developed in O(N) phi^4 theory. It is proved that (i)…
