A method to derive material-specific spin-bath model descriptions of materials displaying prevalent spin physics
Benedikt M. Schoenauer, Nicklas Enenkel, Florian G. Eich +4
Magnetism and spin physics are true quantum mechanical effects and their description usually requires multi reference methods and is often hidden in the standard description of mol…
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…
Observation of spin-charge separation and boundary bound states via the local density of states
Benedikt Schoenauer, Peter Schmitteckert, Dirk Schuricht
We numerically calculate the local density of states (LDOS) of a one-dimensional Mott insulator with open boundaries, which is modelled microscopically by a (extended) Hubbard chai…
