耦合Morse振子中测度同步的研究

Measure synchronization in coupled Morse oscillators

研究了两耦合Morse振子的集体运动行为,研究表明当增大振子间的耦合强度时会出现测度同步现象.单个Moser振子能量随耦合强度的变化显示测度同步实际对应着分离到混合的转变.在这一转变过程中,确定了耦合Moser振子测度同步转变的临界指数率.而进一步研究振子的相位差随振子间耦合强度变化的关系,发现可以通过耦合振子的相锁定引入序参量用来表征这其中测度同步的相变.

The collective behavior of two coupled Morse oscillators were studied and it was found that, with the coupling intensity being increased, two coupled Morse oscillators would reach measure synchronization （MS）. The scaling relation between MS and the order parameter was found, so as to characterize the phase transition behavior.
