多组分玻色-约瑟夫森结中的部分测度同步

Partial measure synchronization in multi-compopnent Bosonic Josephson junction

研究了耦合多组分(N>2)玻色约瑟夫森结中的集体运动行为,发现分别有部分测度同步及完全测度同步的动力学相变行为发生,用序参量描述了其相变特性,并使用庞加莱截面的分析方法揭示了部分测度同步发生的动力学机制,发现部分测度同步也是由分界线的穿越行为所导致的.

The collective dynamics of multi-component Bosonic Josephson junction （N 〉 2） was studied and a transition from partial measure synchronization to complete measure synchronization has been found. Order paramters were computed to describe transitions between measure desynchronization, partial measure synchronization and cornplete measure synchronization. The dynamical mechanism behind the partial measure synchronization transition was revealed by applying the Poincare section analysis, and it was shown that this dynamical transition was caused by the crossing of the separatrix.
