Vibration-mediated correlation effects in the transport properties of a benzene molecule
Michael Knap, Enrico Arrigoni, Wolfgang von der Linden
We theoretically analyze correlation effects on the transport properties of a benzene molecule that are mediated by interactions between the motion of the nuclei and the transmitte…
Nonequilibrium Dynamical Mean Field Theory: an auxiliary Quantum Master Equation approach
Enrico Arrigoni, Michael Knap, Wolfgang von der Linden
We introduce a versatile method to compute electronic steady state properties of strongly correlated extended quantum systems out of equilibrium. The approach is based on dynamical…
Spectral moment sum rules for the retarded Green's function and self-energy of the inhomogeneous Bose-Hubbard model in equilibrium and nonequilibrium
J. K. Freericks, V. Turkowski, H. R. Krishnamurthy +1
We derive expressions for the zeroth and the first three spectral moment sum rules for the retarded Green's function and for the zeroth and the first spectral moment sum rules for…
Steady-state spectra, current and stability diagram of a quantum dot: a non-equilibrium Variational Cluster Approach
Martin Nuss, Christoph Heil, Martin Ganahl +4
We calculate steady-state properties of a strongly correlated quantum dot under voltage bias by means of non-equilibrium Cluster Perturbation Theory and the non-equilibrium Variati…
Time dependent impurity in ultracold fermions: orthogonality catastrophe and beyond
Michael Knap, Aditya Shashi, Yusuke Nishida +3
Recent experimental realization of strongly imbalanced mixtures of ultracold atoms opens new possibilities for studying impurity dynamics in a controlled setting. We discuss how th…
Characterization of Mott-insulating and superfluid phases in the one-dimensional Bose--Hubbard model
Satoshi Ejima, Holger Fehske, Florian Gebhard +4
We use strong-coupling perturbation theory, the variational cluster approach (VCA), and the dynamical density-matrix renormalization group (DDMRG) method to investigate static and…
