The Euler-Kockel-Heisenberg Lagrangian at Finite Temperature

arXiv:hep-th/0210031

Abstract

In the present work we investigate temperature effects on the spinor and scalar effetive QED in the context of Thermo Field Dynamics. Following Weisskopf's zero-point energy method, the problem of charge renormalization is reexamined and high temperature contributions are extracted from the thermal correction for the Lagrangian densities.
