论文摘要
相互作用的声子与相反动量的成对相关性的声子气体的相变是研究。开发了一种在自洽场模型框架内描述此类声子系统的方法，并计算了其热力学特征。结果表明，具有配对相关性的声子气体可以在不稳定的热力学平衡状态下存在。讨论了在这样的阶段对固体进行实验观察的可能性。
The phase transition to the state of a phonon gas with pairwise correlations of interacting phonons with opposite momenta is studies. A method for describing such phonon systems within the framework of the self-consistent field model is developed and their thermodynamic characteristics are calculated. It is shown that a phonon gas with pair correlations can exist in a state of unstable thermodynamic equilibrium. The possibility of experimental observation of a solid in such a phase is discussed.
