Abstract:

Projekt: Quantum Thermalization Dynamics Description: Generic, clean quantum many-body systems approach a thermal equilibrium after a long time evolution. In order to reach a global equilibrium, conserved quantities have to be transported across the whole system which is a rather slow process governed by diffusion. By contrast, the scrambling of quantum information is ballistic and hence can be characterized by a "butterfly" velocity. One way of describing the propagation of quantum information is to study out-of-time ordered (OTO) correlation functions, which are unconventional correlation functions with time arguments that are not time ordered. Using matrix-product-state based and Krylov space based numerical simulations, we will compute such correlators in strongly interacting many-body systems. This allows us to uncover the route to local equilibration and information scrambling in generic isolated quantum many-body systems.
