报告摘要：

Black Holes are amongst the strangest objects in the universe. They form from the collapse of matter into an object whose gravitational pull is so strong, nothing can escape from them. Yet a black hole also radiates heat like a blackbody, with a temperature equal to its  surface gravity, an entropy equal to its area, and an energy equal to its mass. Over the past 10 years we have come to understand the vacuum energy — as embodied by a cosmological constant — plays a pivotal role in the thermodynamic behaviour of black holes. Mass becomes chemical enthalpy, the notion of a thermodynamic volume appears, and black holes exhibit a broad range of chemical phenomena, including liquid/gas phase transitions similar to a Van der Waals fluid, triple points similar to that of water, re-entrant phase transitions that appear in gels and heat engines. Under certain conditions they can even behave like superfluid helium! Now known as “Black Hole Chemistry”, I will review this subject and then go on to describe new work that is providing a pathway toward understanding these phenomena from the perspective of Gauge-Gravity duality, in which phase transitions in the (gravitational) bulk become dual to phase transitions in the dual gauge theory.
