Typical relaxation dynamics to equilibrium, thermal or non-thermal, of isolated many-body quantum systems — •Ben Niklas Balz and Peter Reimann — Fakultät für Physik, Universität Bielefeld, Germany

In the recent past, typicality arguments were used extensively to corroborate that isolated quantum many-body systems equilibrate and that the associated steady state is naturally given by the microcanonical ensemble. These statements are usually derived making use of uniformly distributed unitary transformations (Haar measure) and therefore do not take conserved quantities into account. In the following we are going to present an adapted typicality technique, employ it to derive the corresponding relaxation dynamics and present numerical as well as experimental data in its support.
