Disordered binary harmonic chains with site-dependent force constants
A hierarchical lattice model for a disordered two-component one-dimensional harmonic chain with three force constants, corresponding to the three possible pairs of nearest neighbors, is studied. Differences of as little as 20% between the various force constants can appreciably modify the density of states. These changes in the spectrum allow one to roughly characterize which type of interactio...
متن کاملScaling theory of heat transport in quasi-one-dimensional disordered harmonic chains.
We introduce a variant of the banded random matrix ensemble and show, using detailed numerical analysis and theoretical arguments, that the phonon heat current in disordered quasi-one-dimensional lattices obeys a one-parameter scaling law. The resulting β function indicates that an anomalous Fourier law is applicable in the diffusive regime, while in the localization regime the heat current dec...
متن کاملDelocalization in disordered chains with random symmetrical impurities
We study in this paper, with the context of a tight-binding on-side model, the electronic properties of one-dimensional random lattices with correlated impurities. We show that, when symmetrical impurities εbεcεb are inserted in a host chain of site energy εa and a constant hopping interaction V , diffusion will occur even when εc is random. We provide analytic expressions for the transmittance...
متن کاملModeling wave propagation in damped waveguides of arbitrary cross-section
In this paper the Semi-Analytical Finite Element (SAFE) method for modeling guided wave propagation is extended to account for linear viscoelastic material damping. Linear viscoelasticity is introduced by allowing for complex stiffness constitutive matrices for the material. Dispersive characteristics of viscoelastic waveguides, such as phase velocity, attenuation, energy velocity and cross-sec...
