From black holes to strange metals: many-body physics through a gravitational lens
In the last ten years string theory has revealed a surprising and deep connection between gravity and many-body physics. Puzzling issues in quantum gravity can now be formulated as questions in a many-body system without gravity, where conventional quantum mechanics applies. Alternatively, difficult questions in some strongly coupled many-body systems can be answered by simple calculations in classical gravity. The physical intuition behind this connection will be briefly described, as well as new insights into the quantum nature of black holes that have been obtained. I will then focus on some recent work where the connection has been used to study strongly correlated fermionic systems, with possible applications to the strange metal phase of the cuprate high temperature superconductors.

Refreshments will be served in CP 179 at 3:15 PM
