Dual-Fermion approach to Non-equilibrium strongly correlated problems
C. Jung, A. Lieder, S. Brener +6
We present a generalization of the recently developed dual fermion approach introduced for correlated lattices to non-equilibrium problems. In its local limit, the approach has bee…

Measuring spin and charge correlations via tunneling-current conductance fluctuations
Kelly R. Patton, Hartmut Hafermann, Sergej Brener +2
Scanning tunneling miscoscopy is one of the most powerful spectroscopic tools for single-electron excitations. We show that the conductance fluctuations, or noise in the conductanc…

Semiclassical theory of electron drag in strong magnetic fields
Sergej Brener, Walter Metzner
We present a semiclassical theory for electron drag between two parallel two-dimensional electron systems in a strong magnetic field, which provides a transparent picture of the mo…
