Hubbard-Holstein Model with Dispersive Phonons — •Patrick Haase, Sebastian Fuchs, and Thomas Pruschke — Georg-August Universität, Göttingen, Deutschland

We investigate the local density-of-states in a Hubbard-Holstein model with dispersive phonons. We solve the model in the dynamical mean field approximation using a continuous-time quantum Monte Carlo solver. We extract the local density of states from the imaginary time Green's function by means of the Maximum Entropy method.
