Analytic stochastic treatment of a nonlinear quantum model with negative diffusion
Roberta Zambrini, Stephen M. Barnett
We apply a proposal of Yuen and Tombesi, for treating stochastic problems with negative diffusion, to the analytically soluble problem of the single-mode anharmonic oscillator. We…

Macroscopic quantum fluctuations in noise-sustained optical patterns
Roberta Zambrini, Stephen M. Barnett, Pere Colet +1
We investigate quantum effects in pattern-formation for a degenerate optical parametric oscillator with walk-off. This device has a convective regime in which macroscopic patterns…
