Abstract:
The functional integral approach to real time quantum field
theory at finite temperature is reconsidered to include
boundary conditions for the electromagnetic field strength tensor
on ideal conducting plates. The expression for the generating
functional for real time thermodynamic Green's functions is worked out.
Thereby a closed expression is obtained for the photon propagator
at finite temperature respecting the appropriate boundary conditions.
Within the real time formalism the wellknown zero order results for
enery, free energy and Casimir force are rederived. Using a special
perturbation theoretic expansion of the free energy the second order
radiative corrections to the Casimir effect for different physical
situations are determined.
