Thermodynamic Stability and Fluctuations of the (2+1)-dimensional GMG Warped Black Hole

Tsvetan Vetsov

We investigate the thermodynamic stability and the stochastic thermal fluctuations of the warped black hole solution in three-dimensional General Massive Gravity. We demonstrate th…

Optimal Control Theory of the (2+1)-Dimensional BTZ Black Hole

M. Radomirov, R. C. Rashkov, G. S. Stoilov +1

We apply a finite-time geometric optimization framework to investigate thermal fluctuations and (non)equilibrium optimal processes in the -dimensional BTZ black hole. Employ…

From Heun to Painlevé on Sasaki-Einstein Spaces and Their Confluent Limits

V. Avramov, H. Dimov, M. Radomirov +2

The aim of this paper is to study the effect of isomonodromic deformations of the evolution of scalar fields in Sasaki-Einstein spaces in the context of holography. Here we analyze…
