Atomic vibrations in disordered systems: Comparison of disordered diamond lattices and a realistic amorphous silicon model
J. K. Christie, S. N. Taraskin, S. R. Elliott
Force-constant and positional disorder have been introduced into diamond lattice models in an attempt to mimic the vibrational properties of a realistic amorphous silicon model. Ne…
Disorder-Induced Vibrational Localization
J. J. Ludlam, S. N. Taraskin, S. R. Elliott
The vibrational equivalent of the Anderson tight-binding Hamiltonian has been studied, with particular focus on the properties of the eigenstates at the transition from extended to…
Spatial decay of the single-particle density matrix in tight-binding metals: +AFwAXA- analytic results in two dimensions
S. N. Taraskin, P. A. Fry, Xiadong Zhang +2
Analytical results for the asymptotic spatial decay of the density matrix in the tight-binding model of the two-dimensional metal are…
Vector vibrations and the Ioffe-Regel crossover in disordered lattices
S. N. Taraskin, S. R. Elliott
The spectral density for vector vibrations in the f.c.c. lattice with force-constant disorder is analysed within the coherent potential approximation. The phase diagram showing the…
Instantaneous frequency and amplitude identification using wavelets: Application to glass structure
J. D. Harrop, S. N. Taraskin, S. R. Elliott
This paper describes a method for extracting rapidly varying, superimposed amplitude- and frequency-modulated signal components. The method is based upon the continuous wavelet tra…
Disorder-induced zero-energy spectral singularity for random matrices with correlations
S. N. Taraskin, S. R. Elliott
A zero-energy mid-band singularity has been found in the energy spectrum of random matrices with correlations between diagonal and off-diagonal elements typical of vibrational prob…
