Descripción
The effects induced by the quantum vacuum fluctuations of one massless real scalar field on a configuration of two partially transparent plates are investigated. The physical properties of the infinitely thin plates are imulated by means of Dirac- ? ? ? ? point interactions. It is shown that the distortion caused on the fluctuations by this external background gives rise to a generalization of Robin boundary conditions. The T operator for potentials concentrated on points with nondefined parity is evaluated with total generality. The quantum vacuum interaction energy between the two plates is computed in several dimensions using the T G T G formula to find positive, negative, and zero Casimir energies. The parity properties of the ? ? ? ? potential demands that one distinguish between opposite and identical objects. It is shown that between identical sets of ? ? ? ? plates, repulsive, attractive, or null quantum vacuum forces arise. However, there is always attraction between a pair of opposite ? ? ? ? plates.
