本文研究玻璃中玻色峰与振动相位的关系，发现玻色峰伴随振动从局域化到扩展非波状的转变，并与相位相干性和空间周期性最大值一致，为玻色峰的微观起源提供了新见解。
AI 中文摘要
玻色峰是玻璃态和无序系统中常见的振动特征，被描述为对德拜模型标度（$g({E}){\propto}{E}^2$）的偏离。尽管引起了广泛关注，但振动的微观本质仅被零星地讨论。在此，我们报告了玻色峰如何与从局域化到扩展但非波状的交叉同时出现，并与相位相干性和空间周期性的最大值相吻合。我们的分析为广泛玻璃中玻色峰的微观起源提供了新的见解。
英文摘要
The boson peak is a vibrational feature commonly found in glassy and disordered systems described as the deviation from the scaling of the Debye model ($g({E}){\propto}{E}^2$). Despite much interest, the microscopic nature of the vibrations is only anecdotally discussed. Here we report how the boson peak appears in conjunction with a crossover from localized to extended but non-wave-like and coincide with a maximum in phase coherence and spatial periodicity. Our analyses provide new insights into the microscopic origin of the boson peak across a wide range of glasses.
