Continuous-Time Quantum Monte Carlo Approach to Strongly Correlated Nonlinear Transport — •Andreas Dirks1, Thomas Pruschke1, and Philipp Werner2 — 1Institut für Theoretische Physik, Universität Göttingen — 2Institut für Theoretische Physik, ETH Zürich
The tremendous progress in nano structuring made a broad variety of physical phenomena of quantum impurity systems experimentally accessible through transport measurements. However, computational methods for a reliable description of strongly correlated transport are still rare. We investigate the application of continuous-time Quantum Monte Carlo algorithms to the imaginary-time formalism introduced by Han and Heary [1].
