Emparan García de Salazar, Roberto A.2010-05-062010-05-0619950556-2821https://hdl.handle.net/2445/12357We point out that using the heat kernel on a cone to compute the first quantum correction to the entropy of Rindler space does not yield the correct temperature dependence. In order to obtain the physics at arbitrary temperature one must compute the heat kernel in a geometry with different topology (without a conical singularity). This is done in two ways, which are shown to agree with computations performed by other methods. Also, we discuss the ambiguities in the regularization procedure and their physical consequences.4 p.application/pdfeng(c) The American Physical Society, 1995TermodinàmicaTeoria quàntica de campsPartícules (Física nuclear)Equacions d'estatThermodynamicsQuantum field theoryParticles (Nuclear physics)Equations of stateinfo:eu-repo/semantics/article510685info:eu-repo/semantics/openAccess
