Building an AdS/CFT superconductor
Sean A. Hartnoll, Christopher P. Herzog, Gary T. Horowitz
We show that a simple gravitational theory can provide a holographically dual description of a superconductor. There is a critical temperature, below which a charged condensate for…
Impure AdS/CFT
Sean A. Hartnoll, Christopher P. Herzog
We study momentum relaxation due to dilute, weak impurities in a strongly coupled CFT, a truncation of the M2 brane theory. Using the AdS/CFT correspondence, we compute the relaxat…
Strings on conifolds from strong coupling dynamics: quantitative results
David E. Berenstein, Sean A. Hartnoll
Three quantitative features of string theory on AdS_5 x X_5, for any (quasi)regular Sasaki-Einstein X_5, are recovered exactly from an expansion of field theory at strong coupling…
A phase transition in commuting Gaussian multi-matrix models
Ofer Aharony, Sean A. Hartnoll
We analyze in detail a second order phase transition that occurs in large N Gaussian multi-matrix models in which the matrices are constrained to be commuting. The phase transition…
Ohm's Law at strong coupling: S duality and the cyclotron resonance
Sean A. Hartnoll, Christopher P. Herzog
We calculate the electrical and thermal conductivities and the thermoelectric coefficient of a class of strongly interacting 2+1 dimensional conformal field theories with anti-de S…
Hall conductivity from dyonic black holes
Sean A. Hartnoll, Pavel Kovtun
A class of strongly interacting 2+1 dimensional conformal field theories in a transverse magnetic field can be studied using the AdS/CFT duality. We compute zero momentum hydrodyna…
