In particular\, I will review the theoretical evidence that classical space-time geometry emerge s from the entanglement of more fundamental quantum mechanical degrees of freedom\, and that -- in a sense -- space-time *is* entanglement. This has led to the idea that Einstein’s theory of general relativity\, which desc ribes the fluctuating geometry of space-time\, is a chaotic quantum mechan ical system much like a random matrix theory. In making this precise\, we will discover some interesting mathematics. For example\, the Siegel-Weil formula of number theory allows us to interpret the average over a space o f quantum mechanical systems as a the sum over hyperbolic three-manifolds (essentially\, states of a black hole) in quantum gravity. This comes from an analogy - and in some cases an equivalence - between general relativit y and the theory of random lattices (or sphere packings) in high dimension . Similarly\, the Hawking’s famous formula for the entropy of a black hole leads to a new conjecture for the number of holomorphic sections of line bundles over the moduli space of Riemann surfaces. This talk is intended t o be accessible to mathematicians without a specialized physics background .\n\n\n \n \n \n Lien ZOOM Link\n \n \n \n\n DTSTART:20251010T193000Z DTEND:20251010T203000Z SUMMARY:Alex Maloney (ɬ﷬) URL:/qls/channels/event/alex-maloney-mcgill-university -368192 END:VEVENT END:VCALENDAR
