Thermodynamic properties of the Hubbard model — •Patrick Haase1, Sebastian Fuchs1, Mark Jarrell2, and Thomas Pruschke11Institut für Theoretische Physik, Universität Göttingen, Friedrich-Hund-Platz 1, D-37075 Göttingen, Germany — 2Louisiana State Universtity, Baton Rouge, LA 70803, USA

We calculate the temperature dependence of the internal energy of the Hubbard model in the dynamical mean field approximation using continuous-time quantum Monte Carlo simulations. We fit the energy data with the density of states of a non-interacting system. With this density of states we are able to calculate thermodynamic properties like the entropy, which is not directly accessible by Monte Carlo simulations.
