Seminar: Perdo Ribeiro

It is a pleasure to invite to this years first Quantum seminar.

Perdo Ribero from the University of Lisbon is presently our guest at the Hub. Upcoming Monday, the 22nd, he will tell us a bit about one of his research interests, namely Random matrices on dissipative quantum dynamics

Time and place: Room PS523 in P35, OsloMet. 12.00-13.00.

Abstract:

Understanding the dissipative dynamics of complex quantum systems is essential to describe quantum matter at large time scales. However, even within a simplified Markovian description, studying the spectral and steady-state properties of Lindblad operators remains a challengiing task. In this talk, we present some novel insights into universal features of generic open quantum systems under Markovian dissipation by using ensemble averaging based on (non-Hermitian) random matrices. We examine three representative cases: quadratic Liouvilians, dissipative SYK models, and fully random Liouvilian operators. For this last example, we present a recent systematic classification of many-body Lindblad superoperators based on the properties of the Lindbladian under antiunitary symmetries and unitary involutions.
