我们报告的理论研究的功率谱动力学的负有效质量（NEM）p+pp+振荡器的太赫兹（THz）电磁辐射的影响下。可能的类型的传输状态（周期性或混沌）和它们之间的过渡检查与辐射的强度和频率作为控制参数。当驱动频率固定为自激振荡频率乘以黄金比例的倒数时，所得到的功率谱模式显示出非常复杂的马赛克场景，具有高阶混合频率的自相似出现。
We report on a theoretical investigation of power spectrum dynamics in negative-effective-mass (NEM) p+pp+ oscillators under the influence of terahertz (THz) electromagnetic radiation. Possible types of transport states (periodic or chaotic) and transitions between them are examined with the intensity and frequency of the radiation as controlling parameters. When the driving frequency is fixed to the self-oscillating frequency times the inverse Golden ratio, the resulting power spectrum pattern displays a very complex mosaic scenario with a self-similar emergence of high-order mixing frequencies.
