Equilibration of isolated quantum systems due to restrictions in the experimental set-up — •Ben Niklas Balz — Bielefeld University, Germany

We will explore in what sense and under which conditions isolated quantum many-body systems equilibrate. To estimate the deviations from the equilibrium state a more realistic distinguishability measure than the ones used in [1,2] will be developed, taking into account how often observables with a certain set of outcomes are measured. As a consequence new insights which physical parameters influence equilibration dynamics in what way can be gained. This might be of theoretical importance contributing to the understanding of thermalization [3] or can be used to give more accurate bounds on equilibration times [4,5].
