Nontrivial self-consistent backreaction of quantum fields in 2D dilaton gravity
We consider (1+ 1)-dimensional dilatonic black hole with two horizons, canonical
temperatures of which do not coincide. We show that the presence of quantum fields in such …

On the global temperature of the Schwarzschild–de Sitter spacetime
GE Volovik - JETP Letters, 2023 - Springer
It is shown that the Schwarzschild–de Sitter spacetime has the universal temperature. This
temperature describes the thermal processes of decay of the composite particles and the …

Hot spaces with positive cosmological constant in the canonical ensemble: de Sitter solution, Schwarzschild–de Sitter black hole, and Nariai universe
JPS Lemos, OB Zaslavskii - Physical Review D, 2024 - APS
In a space with fixed positive cosmological constant Λ, we consider a system with a black
hole surrounded by a heat reservoir at radius R and fixed temperature T, ie, we analyze the …

Is the Euclidean path integral always equal to the thermal partition function?
DV Diakonov - Journal of High Energy Physics, 2024 - Springer
A bstract The Euclidean path integral is compared to the thermal (canonical) partition
function in curved static space-times. It is shown that if spatial sections are non-compact and …
