ITMP Seminar "Around a quantum chaos"

Dear Colleagues,

We are pleased to announce the special in-person seminar of the "270th Anniversary of MSU" series will be held on Wednesday, Feb 19, 18:00 (Moscow time).

Speaker: Dr. Alexander Gorsky, Institute for Information Transmission Problems, RAS
Title: Around a quantum chaos
Abstract: I will discuss some aspects of a diagnostics of a quantum chaos. It will be argued that in quite general setting there is the late-time transition from Gauss to KPZ scaling in the autocorrelators evaluated in the Krylov basis. In the DSSYK model similar analysis yields the transition between the KPZ to superdiffusion in the fluctuations of the Krylov complexity. Other approach to identification of quantum chaos is based on the geometry of parameter space. The three regimes for the 2-dimensional parameter space in matrix models have been identified. The talk is based on 2406.02782, 2411.11968 and works in progress.
