Renormalization group approach to field theory at finite temperature
- Department of Physics, Duke University, P.O. Box 90305, Durham, North Carolina 27708-0305 (United States)
Scalar field theory at finite temperature is investigated via an improved renormalization group prescription which provides an effective resummation over all possible nonoverlapping higher loop graphs. Explicit analyses for the {lambda}{phi}{sup 4} theory are performed in {ital d}=4 Euclidean space for both low and high temperature limits. We generate a set of coupled equations for the mass parameter and the coupling constant from the renormalization group flow equation. Dimensional reduction and symmetry restoration are also explored with our improved approach.
