M. Bordag, K. Scharnhorst: O(alpha) radiative correction to the Casimir energy for penetrable mirrors. Physical Review Letters 81:18(1998)3815-3818 (DOI: 10.1103/PhysRevLett.81.3815) [arXiv:hep-th/9807121]. [INSPIRE record]

Abstract: The leading radiative correction to the Casimir energy for two parallel penetrable mirrors (realized by δ-function potentials) is calculated within QED perturbation theory. It is found to be of order alpha like the known radiative correction for ideally reflecting mirrors from which it differs, for a mirror distance much larger than the electron Compton wavelength, only by a monotonic, powerlike function of the frequency at which the mirrors become transparent. This shows that the O(α²) radiative correction calculated recently by Kong and Ravndal for ideally reflecting mirrors on the basis of effective field theory methods remains subleading even for the physical case of penetrable mirrors.
