微波声子Laser（相位器）中的自组织瓶颈与非协调态共存
Self-Organized Bottleneck and Coexistence of Incongruous States in a Microwave Phonon Laser (Phaser)
摘要：
在液氦温度下，研究了粉红红宝石中自主微波声子激光器（相位器）的受激发射（SE）功率谱中出现的规则和混沌精细结构（FS）现象。通过对窄带声子谱的分析，观察到了微波声学FS线演化中的自组织瓶颈现象。声子谱的全景谱实验揭示了整个自旋-声子相位器系统中不协调态（定态、周期态和混沌态）共存的大尺度现象。我们提出了一个可能的方向的基础上的三层元胞自动机（S.D.Makovetskiy和D.N.Makovetskii，arXiv：cond-mat/0410460 v2; S.D.Makovetskiy，arXiv：cond-mat/0602345 v1），模拟一个有界的相位类可激发系统的演化的观察到的现象建模。
英文摘要：
Phenomena of emergence of regular and chaotic fine structure (FS) in stimulated emission (SE) power spectra of an autonomous microwave phonon laser (phaser) have been revealed and investigated experimentally in pink ruby at liquid helium temperatures. The phenomenon of a self-organized bottleneck in evolution of the microwave acoustic FS lines has been observed by means of narrow-range phonon SE spectral analysis. The large-scale phenomenon of coexistence of incongruous (stationary, periodic and chaotic) states in the whole spin-phonon phaser system has been revealed in experiments with panoramic power spectra of phonon SE. We propose a possible direction for modeling of both the observed phenomena on the basis of three-level cellular automata (S.D.Makovetskiy and D.N.Makovetskii, arXiv:cond-mat/0410460v2; S.D.Makovetskiy, arXiv:cond-mat/0602345v1) which emulate evolution of a bounded phaser-like excitable system.
