У оквиру Семинара о струнама, холографији и хаосу, у среду, 21. октобра 2026. године у 12 часова у сали 360 Института за физику у Београду, Хуан-Диего Урбина (Универзитет у Регенсбургу) одржаће предавање:
Periodic orbit theory perspective in JT quantum gravity
САЖЕТАК:
I will give a general account of how the old-fashioned quantum chaos approaches the subject of (short- and late-time) quantum gravitational signatures of chaos, mainly at the level of the spectrum and the OTOCs. I will also briefly connect with eigenstate properties, including the Random Wave Model. I will then address the individual-system versus ensemble interpretation of quantum gravity from a quantum chaos perspective. Due to its chaotic classical limit, motion on hyperbolic manifolds shows all universal signatures of quantum chaos. These properties imply a possible duality to Jackiw-Teitelboim-type quantum gravity at the level of a single system instead of an ensemble of systems like matrix theories and SYK models.
