Characterization of the Mott-insulating phase in the one-dimensional fermionic Hubbard model — •Daniel Duarte, Daniela Pfannkuche, and Marta Prada — I. Institut für Theoretische Physik, Universität Hamburg

In general, many-body long range correlations after a localized quench show non-trivial behavior. We focus on the one dimensional Hubbard model in the Mott-insulating phase and we investigate the evolution of the characteristic long range correlations. The spatial dependence of the correlation functions on the interaction strength is investigated at low temperatures. Furthermore, the spatial-temporal spread of the correlations after a sudden localized perturbation is calculated within a many-body description. Our analysis is based on a density matrix renormalization group approximation.
