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…

Gravitational wave memory and its effects on particles and fields
Abraham I. Harte, Thomas B. Mieling, Marius A. Oancea +1
Gravitational wave memory is said to arise when a gravitational wave burst produces changes in a physical system that persist even after that wave has passed. This paper analyzes g…

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.…
