Entanglement Spectra of Interacting Fermions in Quantum Monte Carlo SimulationsFakher F. Assaad1, Thomas C. Lang2, and •Francesco Parisen Toldin11Institut für Theoretische Physik und Astrophysik, Universität Würzburg, Germany — 2Department of Physics, Boston University, U.S.A.

In a recent article T. Grover introduced a simple method to compute Renyi entanglement entropies in the realm of the auxiliary field quantum Monte Carlo algorithm [1]. Here, we further develop this approach and provide a stabilization scheme to compute higher order Renyi entropies and an extension to access the entanglement spectrum [2]. The method is tested on systems of correlated topological insulators.
