Serbyn Group
Quantum Dynamics and Condensed Matter Theory
How do isolated quantum systems behave when prepared in a highly non-equilibrium state? How can such quantum systems avoid the ubiquitous relaxation to a thermal equilibrium? How can we gain novel insights into properties of quantum matter using modern nonequilibrium probes? These and other open questions in the field of quantum non-equilibrium matter are the focus of the Serbyn group.
The majority of isolated quantum systems thermalize – i.e. they reach thermal equilibrium when starting from non-equilibrium states. The first research direction of the Serbyn group is to understand mechanisms of thermalization breakdown. Many-body localized systems present one generic example of thermalization breakdown due to the presence of strong disorder. The Serbyn group is studying properties of many-body localized phase and phase transition into thermalizing phase. Kinetically constrained models present another class of systems with some signatures of thermalization breakdown. The Serbyn group is actively working on non-equilibrium properties of quantum models with constrained dynamics. A second area of interest to the Serbyn group is related to non-equilibrium probes in condensed matter systems.
