Numerical analysis of the vibrational eigenmodes of a 2D disordered lattice
Source abstract
Abstract
The vibrational modes in the optic band of a 2D lattice with varying degrees of force-constant disorder have been investigated. States at the band edges are localized and other states are prelocalized. The phase boundary marking the transition between such states has been determined as a function of force-constant disorder and mode frequency. It has been demonstrated that the prelocalized states are multifractal in nature.
