Casimir effect in a wormhole spacetime

We consider the Casimir effect for quantized massive scalar field with non-conformal coupling \(\xi\) in a spacetime of wormhole whose throat is rounded by a spherical shell. In the framework of zeta-regularization approach we calculate a zero point energy of scalar field. We found that depending on...

Description
Summary:We consider the Casimir effect for quantized massive scalar field with non-conformal coupling \(\xi\) in a spacetime of wormhole whose throat is rounded by a spherical shell. In the framework of zeta-regularization approach we calculate a zero point energy of scalar field. We found that depending on values of coupling \(\xi\), a mass of field \(m\), and/or the throat's radius \(a\) the Casimir force may be both attractive and repulsive, and even equals to zero.
