Transport at criticality
A. Buchel, C. Pagnutti
We study second order phase transitions in non-conformal holographic models of gauge theory/string theory correspondence at finite temperature and zero chemical potential. We compu…
sQGP as hCFT
Alex Buchel, Michal P. Heller, Robert C. Myers
We examine the proposal to make quantitative comparisons between the strongly coupled quark-gluon plasma and holographic descriptions of conformal field theory. In this note, we ca…
Relaxation time of non-conformal plasma
Alex Buchel
We study effective relaxation time of viscous hydrodynamics of strongly coupled non-conformal gauge theory plasma using gauge theory/string theory correspondence. We compute leadin…
Causality of Holographic Hydrodynamics
Alex Buchel, Robert C. Myers
We study causality violation in holographic hydrodynamics in the gauge theory/string theory correspondence, focussing on Gauss-Bonnet gravity. The value of the Gauss-Bonnet couplin…
Radiative Corrections in Vector-Tensor Models
A. Buchel, F. A. Chishtie, M. T. Hanif +3
We consider a two-form antisymmetric tensor field ϕminimally coupled to a non-abelian vector field with a field strength F. Canonical analysis suggests that a pseudoscalar mass ter…
Exotic Hairy Black Holes
Alex Buchel, Chris Pagnutti
We study black hole solutions in asymptotically AdS_4 spacetime with scalar hair. Following AdS/CFT dictionary these black holes can be interpreted as thermal states of 2+1 dimensi…
Hydrodynamics of the cascading plasma
Alex Buchel
The cascading gauge theory of Klebanov et.al realizes a soluble example of gauge/string correspondence in a non-conformal setting. Such a gauge theory has a strong coupling scale L…
Relativistic Conformal Magneto-Hydrodynamics from Holography
Evgeny I. Buchbinder, Alex Buchel
We use the AdS/CFT correspondence to study first-order relativistic viscous magneto-hydrodynamics of (2+1) dimensional conformal magnetic fluids. It is shown that the first order m…
