    • Abstract


      We investigate the effect of spatially correlated disorder on the Anderson transition of phonons in three dimensions using a Green’s function-based approach, namely, the typical medium dynamical cluster approximation, inmass-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 threedimensional disordered system with an increase in the strength of correlations.
