Remarks on the thermofield double state in 4D black hole background
Prokopii A. Anempodistov
Recently it was shown that there is an anomalous singularity of propagators in spacetimes with horizons for thermal states with non--canonical temperatures. In this paper we extend…

Heating up an environment around black holes and inside de Sitter space
E. T. Akhmedov, P. A. Anempodistov, K. V. Bazarov +2
We study quantum fields on spacetimes having a bifurcate Killing horizon by allowing the possibility that left- and right- (in-going and out-going) modes have different temperature…

Corrections to the Aretakis type behaviour of the metric due to an infalling particle
E. T. Akhmedov, P. A. Anempodistov, I. D. Ivanova
We consider an extremal Reissner-Nordström black hole perturbed by a neutral massive point particle, which falls in radially. We study the linear metric perturbation in the vicinit…
