Abstract
We analyze a single-atom cavity QED model to isolate the dynamic mechanism of stochastic switching between regions of state space associated with mean-field attractors of absorptive bistability. We present evidence from simulations that such switching is correlated with variations in the timings of atomic spontaneous emission events, and we interpret this finding in terms of the dynamics of the coupled intracavity field and atomic dipole. Somewhat surprisingly, both upward and downward (in intracavity photon number) switching transitions may be induced by rapid succession of several atomic emissions. Based on our results we propose an implementation of bidirectional ``toggle'' control for a single-atom optical latch.
