Violation of the holographic bulk viscosity bound
Alex Buchel
Motivated by gauge theory/string theory correspondence, a lower bound on the bulk viscosity of strongly coupled gauge theory plasma was proposed in arXiv:0708.3459. We consider str…
Quantum phase transitions in cascading gauge theory
Alex Buchel
We study a ground state of N=1 supersymmetric SU(K+P) x SU(K) cascading gauge theory of Klebanov et.al [1,2] on R x S^3 at zero temperature. A radius of S^3 sets a compactification…
Holographic bulk viscosity: GPR vs EO
Alex Buchel, Umut Gursoy, Elias Kiritsis
Recently Eling and Oz (EO) proposed a formula for the holographic bulk viscosity, in arXiv:1103.1657, derived from the null horizon focusing equation. This formula seems different…
On Eling-Oz formula for the holographic bulk viscosity
Alex Buchel
Recently Eling and Oz [1] proposed a simple formula for the bulk viscosity of holographic plasma. They argued that the formula is valid in the high temperature (near-conformal) reg…
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…
