Última Propagation of vibrational modes in classical harmonic lattice with correlated disorder 42 SILVA,LEONADE D. DA; RANCIARO NETO,ADHEMAR; SALES,MESSIAS O.; SANTOS,JOSÉ L.L. DOS; MOURA,FRANCISCO A.B.F. DE. Abstract: The vibrational modes with nonzero frequency are localized in harmonic lattice with disordered masses. In our work, we investigated numerically the propagation of vibrational energy in harmonic lattice with long-range correlated disordered masses, which are randomly distributed with power law spectrum S ( k ) ∝ k − α. For α = 0, a standard uncorrelated disordered mass distribution was observed and for α > 0 its distribution exhibits intrinsic long-range correlations. Our procedure was done by the numerical solution of the classical equations for the mass displacement and velocities. Energy flow was investigated after injection of an initial wave-packet with energy E0 and the dynamics of the vibrational energy wave-packet was analyzed. We...
