存在局域势时耦合振子系统的动力学

Dynamics of coupled oscillator systems in presence of a local potential

Alessandro Campa, Shamik Gupta

摘要:

我们考虑一个长程模型的耦合相位只有振荡器受到本地潜力和不断发展的存在下的热噪声。该模型是一个非平凡的推广著名的仓本集体同步模型。我们证明了精确的结果和数值一个令人惊讶的丰富的长时间的行为,在该系统解决到一个静止的状态,可以在或不平衡,并支持全球同步或缺乏它,或者,在一个时间周期同步状态。该系统表现出连续和不连续的相变,以及一个有趣的重入过渡,在该系统中,连续失去和获得的相关的调谐参数的稳定增加的同步。

英文摘要:

We consider a long-range model of coupled phase-only oscillators subject to a local potential and evolving in presence of thermal noise. The model is a non-trivial generalization of the celebrated Kuramoto model of collective synchronization. We demonstrate by exact results and numerics a surprisingly rich long-time behavior, in which the system settles into either a stationary state that could be in or out of equilibrium and supports either global synchrony or absence of it, or, in a time-periodic synchronized state. The system shows both continuous and discontinuous phase transitions, as well as an interesting reentrant transition in which the system successively loses and gains synchrony on steady increase of the relevant tuning parameter.
