Zero-point energy in spheroidal geometries
arXiv:hep-th/0511048 · doi:10.1088/0305-4470/39/21/S43
Abstract
We study the zero-point energy of a massless scalar field subject to spheroidal boundary conditions. Using the zeta-function method, the zero-point energy is evaluated for small ellipticity. Axially symmetric vector fields are also considered. The results are interpreted within the context of QCD flux tubes and the MIT bag model.
