Abstract:  The advent of quantum simulators has made it possible to probe quantum many-body systems with unprecedented resolution. Microscopic read-out of individual degrees of freedom gives access to a far more detailed picture of quantum dynamics than what has been traditionally available in condensed matter physics, and motivates the search for novel universal phenomena. In this talk, I will discuss one such example: "deep thermalization", a recently proposed framework for the emergence of universal randomness in quantum dynamics, based on the statistics of conditional wavefunctions obtained after measuring part of a system. I will present recent results on deep thermalization in tractable quantum circuit models of dynamics, leveraging connections to monitored dynamics and random-matrix theory.
