Abstract—

The stability of a linear chain of dust particles in an external confining force field is studied. It is assumed that the particles are located in a plasma with Maxwellian electrons with a directed flow of cold ions. It is shown that the aperiodic instability of doubling the chain period can develop in a subsonic flow together with the instability of coupled waves. The region of the crystal stability in the space of external parameters is constructed.

线性等离子晶体的稳定性

摘要-

研究了粉尘颗粒线性链在外部约束力场中的稳定性。假定粒子位于具有麦克斯韦电子的等离子体中，并带有定向的冷离子流。结果表明，在亚音速流中，伴随着耦合波的不稳定性，会出现加倍链周期的非周期性不稳定性。构造了在外部参数空间中晶体稳定性的区域。
