Casimir Effect Nearby and Through a Cosmological Wormhole

Abstract

In this letter, we investigate the changes in the quantum vacuum energy density of a massless scalar field inside a Casimir cavity that orbits a wormhole, by considering the cosmological model with an isotropic form of the Morris-Thorne wormhole, embedded in the FLRW universe. In this sense, we examine the effects of its global curvature and scale factor in an instant of the cosmic history, besides the influences of the local geometry as well as of inertial forces, on the Casimirenergy density. We also study the behavior of this quantity when each plate is fixed without rotation at the opposite sides of the wormhole throat, at zero and finite temperatures, taking into account the effective distance between the plates through the wormhole throat.
