Dynamics of photo excitations in 1D-Hubbard systems — •Thomas Köhler and Salvatore R. Manmana — Institut für Theoretische Physik, Universität Göttingen, Germany

We compute the dynamics following a photo excitation in one dimensional Hubbard systems at different temperatures T using matrix product state (MPS) approaches. We discuss the effect of temperature on the propagation of these excitations and give an outlook for systems with time dependent Hamiltonians.
