控制参数连续扫过分叉点的动态分叉用首次通过时间分布来表征。在慢速和快速扫描速率的情况下计算与该分布相关的生成函数。我们的结果与具有随时间变化的腔损耗的 Ar 激光器的实验结果以及早期的数值和模拟模拟结果进行了比较。这里详细阐述了随机框架中延迟分叉的含义。
A dynamical bifurcation in which the control parameter is continuously swept through the bifurcation point is characterized in terms of a first-passage-time distribution. The generating function associated with this distribution is calculated in the cases of slow and fast sweeping rates. Our results are compared with experimental findings in an Ar laser with time-dependent cavity losses and with earlier numerical and analogical simulation results. The meaning of a delayed bifurcation in the stochastic framework presented here is elaborated.
