Mode decomposition and renormalization in semiclassical gravity Roura Crumols, Albert Verdaguer Oms, Enric, 1950- Relativitat (Física) Gravitació Espai i temps Renormalització (Física) Relativity (Physics) Gravitation Renormalization (Physics) Space and time We compute the influence action for a system perturbatively coupled to a linear scalar field acting as the environment. Subtleties related to divergences that appear when summing over all the modes are made explicit and clarified. Being closely connected with models used in the literature, we show how to completely reconcile the results obtained in the context of stochastic semiclassical gravity when using mode decomposition with those obtained by other standard functional techniques. 2010-05-06T08:26:20Z 2010-05-06T08:26:20Z 1999 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0556-2821 https://hdl.handle.net/2445/12311 151953 eng Reproducció digital del document publicat en format paper, proporcionada per PROLA i http://dx.doi.org/10.1103/PhysRevD.60.107503 Physical Review D, 1999, vol. 60, núm. 10, p. 107503-1-107503-4 http://dx.doi.org/10.1103/PhysRevD.60.107503 (c) The American Physical Society, 1999 info:eu-repo/semantics/openAccess 4 p. application/pdf The American Physical Society Articles publicats en revistes (Física de la Matèria Condensada)
