Non-equilibrium Scaling Properties of a Double Quantum Dot System: Comparison between Perturbative Renormalization Group and Flow Equation Approach
V. Koerting, P. Fritsch, S. Kehrein
Since the experimental realization of Kondo physics in quantum dots, its far-from-equilibrium properties have generated considerable theoretical interest. This is due to the intere…

Non-Equilibrium Kondo Model with Voltage Bias in a Magnetic Field
P. Fritsch, S. Kehrein
We derive a consistent 2-loop scaling picture for a Kondo dot in both equilibrium and non-equilibrium situations using the flow equation method. Our analysis incorporates the impor…

Non-Equilibrium Scaling Analysis of the Kondo Model with Voltage Bias
Peter Fritsch, Stefan Kehrein
The quintessential description of Kondo physics in equilibrium is obtained within a scaling picture that shows the buildup of Kondo screening at low temperature. For the non-equili…
