Event Details

Interpreting the cosmological constant as a thermodynamic pressure and its conjugate quantity as a thermodynamic volume, we reconsider the critical behavior of charged AdS black holes. We complete the analogy of this system with the liquid/gas system and study its critical point, which occurs at the point of divergence of specific heat at constant pressure. We calculate the critical exponents and show that they coincide with those of the Van der Waals fluid. For singly spinning black holes in higher dimensions we find a new phenomenon of reentrant phase transitions, in which a monotonic variation of the temperature yields two-phase transitions from large to small and back to large black holes. This situation is similar to that seen in multicomponent liquids.
