Finite-time quantum quenches in the XXZ Heisenberg chain
Benedikt Schoenauer, Dirk Schuricht
We study the time evolution of the two-point correlation functions in the XXZ Heisenberg chain after a finite-time quantum quench in the anisotropy. We compare results from numeric…

Long-lived circulating currents in strongly correlated nanorings
B. M. Schoenauer, N. M. Gergs, P. Schmitteckert +2
We study the time evolving currents flowing in an interacting, ring-shaped nanostructure after a bias voltage has been switched on. The source-to-drain current exhibits the expecte…
