Critical phenomena in N=4 SYM plasma
read the original abstract
Strongly coupled N=4 supersymmetric Yang-Mills plasma at finite temperature and chemical potential for an R-symmetry charge undergoes a second order phase transition. We demonstrate that this phase transition is of the mean field theory type. We explicitly show that the model is in the dynamical universality class of 'model B' according to the classification of Hohenberg and Halperine, with dynamical critical exponent z=4. We study bulk viscosity in the mass deformed version of this theory in the vicinity of the phase transition. We point out that all available models of bulk viscosity at continuous phase transition are in conflict with our explicit holographic computations.

Instability in ${\cal N}=4$ supersymmetric Yang-Mills theory on $S^3$ at finite density
Curvature on S^3 decouples dynamical instabilities in R-charge transport from thermodynamic instabilities in N=4 SYM plasma at finite density, with thermodynamic instability persisting under volume fluctuations.
