Description
Black hole chemistry: thermodynamics with Lambda
Abstract: The mass of a black hole has traditionally been identified with its energy. We describe a new perspective on black hole thermodynamics, one that identifies the mass of a black hole with chemical enthalpy, and the cosmological constant as thermodynamic pressure. This leads to an understanding of black holes from the viewpoint of chemistry, in terms of concepts such as Van der Waals fluids, reentrant phase transitions, and triple points. Both charged and rotating black holes exhibit novel chemical-type phase behaviour, hitherto unseen.
Bio: David Kubiznak’s research focuses on theoretical gravitational physics, black hole thermodynamics, and hidden symmetries of black holes. Currently a professor at Charles University in Prague, he has spentmany years training theoretical physics masters students in the Perimeter Scholars International (PSI) program.
