Entanglement Benchmarked Transport — •Dominik Hörndlein, Vivian França, and Andreas Buchleitner — Physikalisches Institut, Universität Freiburg, Hermann-Herder-Str. 3, 79104 Freiburg im Breisgau, Germany

Quantum transport phenomena in interacting many particle systems can be studied to unprecedented detail with the use of experimentally engineered Hubbard-type hamiltonians. Further on entanglement measures have shown to be sensitive indicators of phase transitions. Such different phases can be associated with very different transport properties, as evident, e.g. for the Anderson and the Mott transition. Therefore, in a numerical study of the Fermi-Hubbard model, we investigate the direct relation between transport and the entanglement properties of the many particle system.
