Ambrus, V.E. and Winstanley, E. orcid.org/0000-0001-8964-8142 (2015) Renormalised fermion vacuum expectation values on anti-de Sitter space-time. Physics Letters B, 749. pp. 597-602. ISSN 0370-2693
Abstract
The Schwinger–de Witt and Hadamard methods are used to obtain renormalised vacuum expectation values for the fermion condensate, charge current and stress-energy tensor of a quantum fermion field of arbitrary mass on four-dimensional anti-de Sitter space–time. The quantum field is in the global anti-de Sitter vacuum state. The results are compared with those obtained using the Pauli–Villars and zeta-function regularisation methods, respectively.
