Non-equilibrium steady state in a periodically driven Kondo model
Markus Heyl, Stefan Kehrein
We investigate the Kondo model with time-dependent couplings that are periodically switched on and off. On the Toulouse line we derive exact analytical results for the spin dynamic…
Sudden interaction quench in the quantum sine-Gordon model
J. Sabio, S. Kehrein
We study a sudden interaction quench in the weak-coupling regime of the quantum sine-Gordon model. The real time dynamics of the bosonic mode occupation numbers is calculated using…
Crossover from adiabatic to sudden interaction quenches in the Hubbard model: Prethermalization and nonequilibrium dynamics
Michael Moeckel, Stefan Kehrein
The recent experimental implementation of condensed matter models in optical lattices has motivated research on their nonequilibrium behavior. Predictions on the dynamics of superc…
Non-equilibrium magnetization dynamics of ferromagnetically coupled Kondo spins
Andreas Hackl, Stefan Kehrein, Matthias Vojta
An analytical description of non-equilibrium phenomena in interacting quantum systems is rarely possible. Here we present one example where such a description can be achieved, name…
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…
Real-time evolution for weak interaction quenches in quantum systems
Michael Moeckel, Stefan Kehrein
Motivated by recent experiments in ultracold atomic gases that explore the nonequilibrium dynamics of interacting quantum many-body systems, we investigate the nonequilibrium prope…
Nonequilibrium Spin Dynamics in the Ferromagnetic Kondo Model
Andreas Hackl, David Roosen, Stefan Kehrein +1
Motivated by recent experiments on molecular quantum dots we investigate the relaxation of pure spin states when coupled to metallic leads. Under suitable conditions these systems…
