Single Qubit Rabi Oscillation Decohered by Many Two-Level Systems
Ren-Shou Huang, Viatcheslav Dobrovitski, Bruce Harmon
Recent experiments on Josephson junction qubits have suggested the existence in the tunnel barrier of bistable two level fluctuators that are responsible for decoherence and 1/f cr…
Decoherence in quantum spin systems
H. De Raedt, V. V. Dobrovitski
Computer simulations of decoherence in quantum spin systems require the solution of the time-dependent Schrodinger equation for interacting quantum spin systems over extended perio…
Quantum oscillations without quantum coherence
V. V. Dobrovitski, H. A. De Raedt, M. I. Katsnelson +1
We study numerically the damping of quantum oscillations and the increase of entropy with time in model spin systems decohered by a spin bath. In some experimentally relevant cases…
Length scales coupling for nonlinear dynamical problems in magnetism
V. V. Dobrovitski, M. I. Katsnelson, B. N. Harmon
The dynamics of real magnets is often governed by several interacting processes taking place simultaneously at different length scales. For dynamical simulations the relevant lengt…
