摘要
An atomic coherent state will evolve to an atomic coherent state under a classical driving field. Under a time-periodic driving field the phase space for the dynamics is S-2 x S-1, so that chaotic motion is possible. We explore the types of motion that can occur for periodically driven atomic coherent states by investigating the properties of the first return map S-2 -%26gt; S-2. The sphere map that we introduce is a generalization of the Kolmogorov-Arnold circle map that is based on the Gauss sphere map. We find mixtures of mode-locking, quasiperiodicity, forward and reverse period-doubling cascades and chaos.
