Mann (University of Waterloo) as part of Tricontinental Quantum Fundamentals Seminar\n\n\n Abstract\nBlack Holes are amongst the strangest objects in the universe. T hey form from the collapse of matter into an object whose gravitational pu ll is so strong\, nothing can escape from them. Yet a black hole also radi ates heat like a blackbody\, with a temperature equal to its surface gravi ty\, an entropy equal to its area\, and an energy equal to its mass. Over the past 15 years we have come to understand that the vacuum energy — a s embodied by a cosmological constant — plays a pivotal role in the ther modynamic behaviour of black holes. Mass becomes chemical enthalpy\, the n otion of a thermodynamic volume appears\, and black holes exhibit a broad range of chemical phenomena\, including liquid/gas phase transitions simil ar 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 cert ain 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 p henomena from the perspective of Gauge-Gravity duality\, in which phase tr ansitions in the (gravitational) bulk become dual to phase transitions in the dual gauge theory.\n LOCATION:https://researchseminars.org/talk/3cqfs/14/ END:VEVENT END:VCALENDAR
