Pair production by and electric field in (1+1)-dimensional de Sitter space Garriga Torres, Jaume Cosmology Relativitat (Física) Gravetat quàntica Teoria de camps (Física) Partícules (Física nuclear) Cosmology Relativity (Physics) Quantum gravity Field theory (Physics) Particles (Nuclear physics) We use the method of Bogolubov transformations to compute the rate of pair production by an electric field in (1+1)-dimensional de Sitter space. The results are in agreement with those obtained previously using the instanton methods. This is true even when the size of the instanton is comparable to the size of the de Sitter horizon. 2010-05-06T08:53:15Z 2010-05-06T08:53:15Z 1994 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0556-2821 https://hdl.handle.net/2445/12335 507978 eng Reproducció digital del document publicat en format paper, proporcionada per PROLA i http://dx.doi.org/10.1103/PhysRevD.49.6343 Physical Review D, 1994, vol. 49, núm. 12, p. 6343-6353 http://dx.doi.org/10.1103/PhysRevD.49.6343 (c) The American Physical Society, 1994 info:eu-repo/semantics/openAccess 4 p. application/pdf The American Physical Society Articles publicats en revistes (Física de la Matèria Condensada)
