We compute energies and energy densities of static electromagnetic flux tubes in three and four spacetime dimensions. Our non-perturbative calculation uses scattering data from the potential induced by the flux tube. The calculation is exact to one-loop order and imposes standard perturbative renormalization conditions. We embed the flux tube in a configuration with zero total flux so that we c...

We study the formation of vacuum condensates in 2 + 1 dimensional QED in the presence of inhomogeneous background magnetic fields. For a large class of magnetic fields, the condensate is shown to be proportional to the inhomogeneous magnetic field, in the large flux limit. This may be viewed as a local form of the integrated degeneracy-flux relation of Aharonov and Casher.

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.
