Decoherence in a Double-Dot Aharonov-Bohm Interferometer
Björn Kubala, David Roosen, Michael Sindel +2
Coherence in electronic interferometers is typically believed to be restored fully in the limit of small voltages, frequencies and temperatures. However, it is crucial to check thi…
Dynamics, Synchronization and Quantum Phase Transitions of Two Dissipative Spins
Peter P. Orth, David Roosen, Walter Hofstetter +1
We analyze the static and dynamical properties of two Ising-coupled quantum spins embedded in a common bosonic bath as an archetype of dissipative quantum mechanics. First, we eluc…
Spectral function of the Anderson impurity model at finite temperatures
Aldo Isidori, David Roosen, Lorenz Bartosch +2
Using the functional renormalization group (FRG) and the numerical renormalization group (NRG), we calculate the spectral function of the Anderson impurity model at zero and finite…
