Ambrus, V.E. and Winstanley, E. orcid.org/0000-0001-8964-8142 (2014) Dirac Fermions on an Anti-de Sitter Background. In: TIM 2013 PHYSICS CONFERENCE. TIM 2013 PHYSICS CONFERENCE, 21–24 November 2013, Timisoara, Romania. AIP Conference Proceedings (1634). , pp. 40-49. ISBN 978-0-7354-1273-6
Abstract
Using an exact expression for the bi-spinor of parallel transport, we construct the Feynman propagator for Dirac fermions in the vacuum state on anti-de Sitter space-time. We compute the vacuum expectation value of the stress-energy tensor by removing coincidence-limit divergences using the Hadamard method. We then use the vacuum Feynman propagator to compute thermal expectation values at finite temperature. We end with a discussion of rigidly rotating thermal states.
