摘要:

在生物振子系综中,常出现仓本振子受温度场影响的时间演化。本文在等间距正则环格点上提出了一个广义的Kuramoto型格点模型,假定每个振子都有一个内能(温度)。我们的晶格模型是从二维自由空间上的群集的物理Cucker-Smale模型推导出来的,假设每个晶格点处的速度场和温度场之间的比率在晶格点上具有均匀的量值。所提出的模型满足熵原理,并表现出紧急动力学的一些充分的框架下制定的初始数据和系统参数。此外,相场渐近趋于仓本相场。

英文摘要:

The temporal evolution of Kuramoto oscillators influenced by the temperature field often appears in biological oscillator ensembles. In this paper, we propose a generalized Kuramoto type lattice model on a regular ring lattice with the equal spacing assuming that each oscillator has an internal energy (temperature). Our lattice model is derived from the thermodynamical Cucker-Smale model for flocking on the 2D free space under the assumption that the ratio between velocity field and temperature field at each lattice point has a uniform magnitude over lattice points. The proposed model satisfies an entropy principle and exhibits emergent dynamics under some sufficient frameworks formulated in terms of initial data and system parameters. Moreover, the phase-field tends to the Kuramoto phase-field asymptotically.
