We use the AdS/CFT correspondence to study the thermodynamics of massive N=2 supersymmetric hypermultiplets coupled to N=4 supersymmetric SU(Nc) Yang-Mills theory in the limits of large Nc and large 't Hooft coupling. In particular, we study the theory at finite baryon number density. At zero temperature, we present an exact expression for the hypermultiplets' leading-order contribution to the free energy, and in the supergravity description we clarify which D-brane configuration is appropriate for any given value of the chemical potential. We find a second-order phase transition when the chemical potential equals the mass. At finite temperature, we present an exact expression for the hypermultiplets' leading-order contribution to the free energy at zero mass.

- Superconductivity from gauge/gravity duality with flavor (2008, background): “ They move from the horizon into the bulk and thus distribute the isospin charge. This stabilizes the system. Let us first describe the unstable configuration in absence of the field A1 3. As known from [17, 9, 2], the non-zero field A3 0 is induced by fundamental strings which are stretched from the D7”
- Holographic phase transitions at finite chemical potential (2007, background): “Let us add that this clarification also highlights a shortcoming of the holographic explorations of the phase diagram of strongly coupled gauge theories here and, for example, in [1, 15, 16, 17, 26, 33].”
