ناجایگزیدگی امواج کشسان در زنجیره هارمونیک بی‌نظم با ثابت فنر تصادفی و همبستگی بلندبرد

Using inverse participation ratio and level statistics analysis, we investigate the localization of the natural modes of a disordered harmonic chain in which the force constants are distributed randomly without correlation as well as with long-range power-law (c ( l ) ~ l-y )  correlation. We find that for a specific value of correlation exponent the localized modes turn to be extended.
