String Theory seminar - Alessandra Gnecchi Seminar

After reviewing properties of BPS black holes, I will present their supersymmetric flow in N=2 four dimensional gauged supergravity, with particular emphasis on electric-magnetic duality properties. I will then describe the holographic renormalization needed to define physical quantities for black holes and black branes in AdS at finite temperature, in presence of scalar and vector fields. The last part of the talk with discuss thermodynamic properties and phase space of black branes in AdS, with the identification of a quantum critical point and its possible holographic interpretation.
