Complex Geodesics in the Nariai Geometry
Lars Aalsma, Mir Mehedi Faruk
We study two-point correlation functions of heavy scalar fields in the Nariai geometry. Utilizing the heat kernel formalism, we obtain this result from a geodesic approximation to…

Limits on the Statistical Description of Charged de Sitter Black Holes
Lars Aalsma, Puxin Lin, Jan Pieter van der Schaar +2
The thermodynamics of de Sitter black holes is complicated by the presence of two horizons and the absence of a globally defined timelike Killing vector. The standard choice of the…
