Thermal radiation in non-static curved spacetimes: quantum mechanical path integrals and configuration space topology
نویسندگان
چکیده
A quantum mechanical path integral derivation is given of a thermal propagator in non-static Gui spacetime. The thermal nature of the propagator is understood in terms of homotopically non-trivial paths in the configuration space appropriate to tortoise coordinates. The connection to thermal emission from collapsing black holes is discussed. Typeset using REVTEX Supported by the Société Académique Vaudoise and by the Swiss National Science Foundation. 1

Quantum mechanical path integrals and thermal radiation in static curved spacetimes
Quantum mechanical path integrals [1–4], also called first quantised path integrals, have been applied to some problems in curved spacetimes [5], such as to cosmological and black-holes issues [6–11]. A remarkable theoretical prediction in semi-classical gravity is that of the thermal and quantum radiation of black holes [12,13]. This result is recovered again in the present paper within the fo...
متن کاملCovariant path integrals and black holes
The thermal nature of the propagator in a collapsed black-hole spacetime is shown to follow from the non-trivial topology of the configuration space in tortoise coordinates by using the path integral formalism. The path integral (PI) formalism is useful to calculate propagators in configuration spaces (CS) endowed with a non-trivial topology, such as in curved spacetimes. Moreover, even if the ...
متن کاملIntegrals over Products of Distributions from Manifest Coordinate Invariance of Perturbation Expansions of Path Integrals in Curved Space
– We show that the requirement of manifest coordinate invariance of perturbatively defined quantum-mechanical path integrals in curved space leads to an extension of the theory of distributions by specifying unique rules for integrating products of distributions. The rules are derived using equations of motion and partial integration, while keeping track of certain minimal features stemming fro...
متن کاملLoop calculations in quantum-mechanical non-linear sigma models
By carefully analyzing the relations between operator methods and the discretized and continuum path integral formulations of quantum-mechanical systems, we have found the correct Feynman rules for one-dimensional path integrals in curved spacetime. Although the prescription how to deal with the products of distributions that appear in the computation of Feynman diagrams in configuration space ...
متن کاملTrace anomalies and the string - inspired definition of quantum - mechanical path integrals in curved space
We consider quantum-mechanical path integrals for non-linear sigma models on a circle defined by the string-inspired method of Strassler, where one considers periodic quantum fluctuations about a center-of-mass coordinate. In this approach one finds incorrect answers for the local trace anomalies of the corresponding n-dimensional field theories in curved space. The quantum field theory approac...
