DOI: 10.1088/1361-6382/aae45b
Abstract: We investigate quantum effects on topological black hole space-times within the framework of quantum field theory on curved space-times. Considering a quantum scalar field, we extend a recent mode-sum regularization prescription for the computation of… read more here.

DOI: 10.1103/physrevd.103.045007
Abstract: We compute the renormalized vacuum polarization for a massless, conformally coupled scalar field on asymptotically anti--de Sitter black hole backgrounds. Mixed (Robin) boundary conditions are applied on the spacetime boundary. We consider black holes with… read more here.

DOI: 10.1142/s0217751x20400308
Abstract: We consider the gravity-induced effects associated with a massless scalar field living in a higher-dimensional spacetime being the tensor product of Minkowski space and spherically-symmetric space with angle deficit. These spacetimes are considered as simple… read more here.
