论文摘要
非谐度（耦合）在田间理论中的影响通常会导致平面波的耗散。人们认为，eNharmonicity和随之而来的平面波耗散可以伴随着宽大的动量状态的出现。在这里，我们表明相同的效果可能导致频率（能量）间隙明确出现的分散性关系。我们讨论了宽大的能量和动量状态以及它们之间的连接的几种显着特性。
The effect of anharmonicity (coupling) in the field theory generally result in dissipation of plane waves. It has been appreciated that anharmonicity and ensuing dissipation of plane waves can be accompanied by the emergence of the gapped momentum state. Here, we show that the same effect can lead to a gapped energy state and a dispersion relation where the frequency (energy) gap emerges explicitly. We discuss several notable properties of gapped energy and momentum states and connections between them.
