Phonons in random alloys: the itinerant coherent-potential approximation
Subhradip Ghosh, Paul L. Leath, Morrel H. Cohen
We present the itinerant coherent-potential approximation(ICPA), an analytic, translationally invariant and tractable form of augmented-space-based, multiple-scattering theory in a…
Universal Susceptibility Variations in 1+1 Dimensional Vortex Glass
Chen Zeng, Paul L. Leath, Terence Hwa
We model a planar array of fluxlines as a discrete solid-on-solid model with quenched disorder. Simulations at finite temperatures are made possible by a new algorithm which circum…
Thermodynamics of Mesoscopic Vortex Systems in 1+1 Dimensions
Chen Zeng, Paul L. Leath, Terence Hwa
The thermodynamics of a disordered planar vortex array is studied numerically using a new polynomial algorithm which circumvents slow glassy dynamics. Close to the glass transition…
Failure Probabilities and Tough-Brittle Crossover of Heterogeneous Materials with Continuous Disorder
B. Q. Wu, P. L. Leath
The failure probabilities or the strength distributions of heterogeneous 1D systems with continuous local strength distribution and local load sharing have been studied using a sim…
Application of Polynomial Algorithms to a Random Elastic Medium
Chen Zeng, Paul L. Leath
A randomly pinned elastic medium in two dimensions is modeled by a disordered fully-packed loop model. The energetics of disorder-induced dislocations is studied using exact and po…
Absence of Two-Dimensional Bragg Glasses
Chen Zeng, Paul L. Leath, Daniel S. Fisher
The stability to dislocations of the elastic phase, or ``Bragg glass'', of a randomly pinned elastic medium in two dimensions is studied using the minimum-cost-flow algorithm for a…
