- We use a local projectional analysis method to investigate theeffect of topological disorder on the vibrational dynamics in a modelglass simulated by molecular dynamics. It is shown that the vibrational eigenmodes in the glass aregenerically related to the corresponding eigenmodes of its crystallinecounterpart via disorder-induced level-repelling and hybridizationeffects. It is demonstrated that the effect of topological disorder in theglass on the dynamical matrix can be simulated by introducingpositional disorder in a crystalline counterpart.
