摘要：

An angular momentum J in a resonant-cavity electromagnetic field exhibits chaos in the time dependence of the expectation value of J(z). This fact is transparently demonstrated using the SU(2) generalized coherent-state picture. Using Hale's averaging theorem, the mechanism of chaos is elucidated and found to be equivalent to a periodically modulated, near-separatrix, pendulum motion. The rotating-wave approximation is also elucidated, and its nonchaos is explained. The modulations that cause chaos result from virtual transitions, and the variance of J(z) initially grows exponentially.
