DESCRIPTION:Speakers: Thomas Morley (University of Sheffield)\nAnti-de Sit
ter spacetime is a solution of Einstein’s equations with a negative cosm
ological constant. This fact allows for unusual black hole solutions with
non-spherical horizon topology. We calculate the renormalised vacuum polar
isation for black holes with spherical\, flat and hyperbolic event horizon
s\, following the “extended coordinates” method\, which uses a mode-su
m representation for the Hadamard parametrix. Renormalisation counter term
s are subtracted from the Green’s function mode-by-mode\, leaving each i
ndividual term manifestly finite.\n\nhttps://conference.ippp.dur.ac.uk/eve
