Stochastic coupling in two modes systems: the weak-strong coupling transition
Dagoberto S. Freitas, M. C. Nemes
We investigate the weak-strong coupling transition of two linearly coupled systems under the influence of a phase fluctuating coupling. In the weak coupling regime the exponential…

Preparation of Schrödinger cat states of a cavity field via coupling to a superconducting charge qubit
Dagoberto S. Freitas, M. C. Nemes
We extend the approach of Ref. [Yu-xi Liu, L. F. Wei, and F. Nori, Europhys. Lett. 67, 941 (2004)] for preparing superposition states of a cavity field interacting with a supercond…
