On the supergravity description of boost invariant conformal plasma at strong coupling
Paolo Benincasa, Alex Buchel, Michal P. Heller +1
We study string theory duals of the expanding boost invariant conformal gauge theory plasmas at strong coupling. The dual supergravity background is constructed as an asymptotic la…
Bulk viscosity of gauge theory plasma at strong coupling
Alex Buchel
We propose a lower bound on bulk viscosity of strongly coupled gauge theory plasmas. Using explicit example of the N=2^* gauge theory plasma we show that the bulk viscosity remains…
The black hole in the throat - thermodynamics of strongly coupled cascading gauge theories
Ofer Aharony, Alex Buchel, Patrick Kerner
We numerically construct black hole solutions corresponding to the deconfined, chirally symmetric phase of strongly coupled cascading gauge theories at various temperatures. We com…
An exact string representation of 3d SU(2) lattice Yang--Mills theory
Florian Conrady, Igor Khavkine
We show that 3d SU(2) lattice Yang--Mills theory can be cast in the form of an exact string representation. The derivation starts from the exact dual (or spin foam) representation…
The Derivative Expansion of the Effective Action and the Renormalization Group Equation
F. A. Chishtie, Junji Jia, D. G. C. McKeon
The perturbative evaluation of the effective action can be expanded in powers of derivatives of the external field. We apply the renormalization group equation to the term in the e…
Dynamical stabilization of runaway potentials and landscape of vacua at finite density
Alex Buchel, Junji Jia, V. A. Miransky
We study a SU(2) gauge theory with a classical complex modulus. Introducing a chemical potential for a conserved modulus hypercharge causes it to become unstable and start condensi…
