相位振子晶格中的行波和紧致子

Traveling waves and Compactons in Phase Oscillator Lattices

Karsten Ahnert, Arkardy Pikovsky

摘要:

我们研究色散耦合相位振子链中的波。两种方法-一个准连续的近似和迭代数值解的晶格方程-让我们来表征不同类型的行波:kovatons,孤立波与指数尾巴,以及一种新的类型的半紧波,是紧凑的一侧。这些波的稳定性进行了研究,使用数值模拟的初值问题。

英文摘要:

We study waves in a chain of dispersively coupled phase oscillators. Two approaches -- a quasi-continuous approximation and an iterative numerical solution of the lattice equation -- allow us to characterize different types of traveling waves: compactons, kovatons, solitary waves with exponential tails as well as a novel type of semi-compact waves that are compact from one side. Stability of these waves is studied using numerical simulations of the initial value problem.
