论文摘要
我们使用基于绿色的函数方法（即典型的媒体动力簇近似（TMDCA））在质量划分的系统中研究了空间相关性障碍对在三个维度的安德森转变的影响。我们从数值上证明，与成对相关性相关性疾病减轻了振动模式的定位。相关驱动的定位转移过渡可以在三维无序系统中出现，相关强度的增加。
We investigate the effect of spatially correlated disorder on the Anderson transition of phonons in three dimensions using a Greens function based approach, namely, the typical medium dynamical cluster approximation (TMDCA), in mass-disordered systems. We numerically demonstrate that correlated disorder with pairwise correlations mitigates the localization of the vibrational modes. A correlation driven localization-delocalization transition can emerge in a three-dimensional disordered system with an increase in the strength of correlations.
