Holographic Entanglement Entropy in Anisotropic Background with Confinement-Deconfinement Phase Transition
Irina Ya. Aref'eva, Alexander Patrushev, Pavel Slepov
We discuss a general five-dimensional completely anisotropic holographic model with three different spatial scale factors, characterized by a Van der Waals-like phase transition be…
Entropy discrepancy and total derivatives in trace anomaly
Amin Faraji Astaneh, Alexander Patrushev, Sergey N. Solodukhin
In this note we address the discrepancy found by Hung, Myers and Smolkin between the holographic calculation of entanglement entropy (using the Jacobson-Myers functional for the ho…
Entropy vs Gravitational Action: Do Total Derivatives Matter?
Amin Faraji Astaneh, Alexander Patrushev, Sergey N. Solodukhin
The total derivatives in the gravitational action are usually disregarded as non-producing any non-trivial dynamics. In the context of the gravitational entropy, within Wald's appr…
Distributional Geometry of Squashed Cones
Dmitri V. Fursaev, Alexander Patrushev, Sergey N. Solodukhin
A regularization procedure developed in [1] for the integral curvature invariants on manifolds with conical singularities is generalized to the case of squashed cones. In general,…
On Determining the Running Coupling from the Effective Action
D. G. C. McKeon, A. Patrushev
The conformal anomaly has provided an expression for the effective action of gauge theories in the presence of a strong background field in terms of the running coupling constant.…
Electrodynamics in a Background Chiral Field
F. T. Brandt, D. G. C. McKeon, A. Patrushev
We consider the one loop effective action in four dimensional Euclidean space for a background chiral field coupled to a spinor field. It proves possible to find an exact expressio…
Eling-Oz Formula for Exotic Hairy Black Holes
Alexander Patrushev
We checked Eling-Oz formula [1] for the bulk viscosity of the holographic fluid dual to the exotic black holes [2]. Initially, Eling and Oz argued that the formula is valid in the…
Can the correlated stability conjecture be saved?
Alex Buchel, Alexander Patrushev
Correlated stability conjecture (CSC) proposed by Gubser and Mitra [1,2] linked the thermodynamic and classical (in)stabilities of black branes. In [3] it was shown that the thermo…
Canonical Analysis of Scalar Fields in Two Dimensional Curved Space
D. G. C. McKeon, Alexander Patrushev
Scalar fields on a two dimensional curved surface are considered and the canonical structure of this theory analyzed. Both the first and second order forms of the Einstein-Hilbert…
