Quantum effects of charged massive scalar fields on charged black hole space-times
Cormac Breen, George Montagnon, Peter Taylor +1
We compute the renormalized expectation values of the scalar condensate, charge current and stress-energy tensor for a massive charged quantum scalar field on a Reissner-Nordstrom…
Vacuum polarization and renormalized stress-energy tensor of spherical thin shells
Julio Arrechea, Cormac Breen, Adrian Ottewill +2
We provide a thorough study of the properties of the Boulware vacuum in the spacetime of a spherical, static thin shell with a Minkowski interior. To this end, we calculate the ren…
The renormalized stress-energy tensor for scalar fields in the Boulware state with applications to extremal black holes
Julio Arrechea, Cormac Breen, Adrian Ottewill +2
We provide a mode-sum prescription to directly compute the renormalized stress-energy tensor (RSET) for scalar fields in the Boulware vacuum. The method generalizes the recently de…
Unruh-DeWitt Particle Detectors in Bouncing Cosmologies
Aindriú Conroy, Peter Taylor
We study semi-classical particle production in non-singular bouncing cosmologies by employing the Unruh-DeWitt model of a particle detector propagating in this class of spacetimes.…
Mode-sum prescription for renormalized expectation values for a charged quantum scalar field on a charged black hole
Cormac Breen, George Montagnon, Peter Taylor +1
We present a new mode-sum prescription for the efficient computation of renormalized expectation values for a massive, charged, quantum scalar field propagating on a curved space-t…
