Effective Field Theories for the Casimir Effect at Finite Temperature

Abstract

We discuss corrections to the Casimir effect at finite temperature and effective field theory. Recently, it has been shown that effective field theories can reproduce radiative corrections to the Casimir energy calculated in full QED. We apply effective field theory methods at finite temperature and reproduce the Casimir free energy. We show that the system undergoes dimensional reduction at high temperature and that it can be described by an effective three-dimensional field theory.
