Geometric Background for Thermal Field Theories
Massimo Blasone, Yuan-Xing Gui, Francis Vendrell
We study a new spacetime which is shown to be the general geometrical background for Thermal Field Theories at equilibrium. The different formalisms of Thermal Field Theory are uni…
Quantum mechanical path integrals and thermal radiation in static curved spacetimes
F. Vendrell
The propagator of a spinless particle is calculated from the quantum mechanical path integral formalism in static curved spacetimes endowed with event-horizons. A toy model, the Gu…
Covariant path integrals and black holes
F. Vendrell, M. E. Ortiz
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 usin…
Some exact results on the CGHS black-hole radiation
F. Vendrell
Theorems on the emission of massless scalar particles by the CGHS black hole are presented. The convergence of the mean number of particles created spontaneously in an arbitrary st…
Thermal radiation in non-static curved spacetimes: quantum mechanical path integrals and configuration space topology
M. E. Ortiz, F. Vendrell
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 homotopic…
A black hole in two-dimensional space-time
F. Vendrell
An imploding shell of radiation is shown to create a 2-D black hole within the framework of the ``R=T'' theory. The radius of the horizon is given by 1/(2M), where M is the mass of…
