Abstract

The nonlinear development stage is studied of the instability of coupled waves in the planar plasma crystal in the external confining force field. It is assumed that the particles are located in plasma consisting of the Maxwellian electrons and the directed flow of cold ions. It is demonstrated that the effect of nonlinearity results either in acceleration of the instability development or in the formation of a time crystal consisting of one or three stable waves. In the space of external parameters, the domains of existence of different phases are constructed.

等离子晶体作为时间晶体

摘要

研究了在外部约束力场中平面等离子体晶体中耦合波的不稳定性的非线性发展阶段。假定粒子位于由麦克斯韦电子和冷离子的定向流组成的等离子体中。结果表明，非线性效应导致不稳定性的加速发展，或者导致由一或三个稳定波组成的时间晶体的形成。在外部参数空间中，构造了不同相的存在域。
