Parametric correlations versus fidelity decay: the symmetry breaking case
H. Kohler, T. Nagao, H. -J. Stöckmann
We derive fidelity decay and parametric energy correlations for random matrix ensembles where time--reversal invariance of the original Hamiltonian is broken by the perturbation. L…
A random matrix theory of decoherence
T. Gorin, C. Pineda, H. Kohler +1
Random matrix theory is used to represent generic loss of coherence of a fixed central system coupled to a quantum-chaotic environment, represented by a random matrix ensemble, via…
Anomalous slow fidelity decay for symmetry breaking perturbations
T. Gorin, H. Kohler, T. Prosen +3
Symmetries as well as other special conditions can cause anomalous slowing down of fidelity decay. These situations will be characterized, and a family of random matrix models to e…
Quantum electrodynamic fluctuations of the macroscopic Josephson phase
H. Kohler, F. Guinea, F. Sols
We study the equilibrium dynamics of the relative phase in a superconducting Josephson link taking into account the quantum fluctuations of the electromagnetic vacuum. The photons…
