Fidelity and criticality in the nonreciprocal Aubry-Andr{é}-Harper model
Chen-Chang Zeng, Zhen Cai, Guang-Heng Wang +1
We study the critical behaviors of the ground and first excited states in the one-dimensional nonreciprocal Aubry-Andr{é}-Harper model using both the self-normal and biorthogonal f…
Test of Replica Theory: Thermodynamics of 2D Model Systems with Quenched Disorder
Simon Bogner, Thorsten Emig, Ahmed Taha +1
We study the statistics of thermodynamic quantities in two related systems with quenched disorder: A (1+1)-dimensional planar lattice of elastic lines in a random potential and the…
High-Order Coupled Cluster Method Calculations for the Ground- and Excited-State Properties of the Spin-Half XXZ Model
R. F. Bishop, D. J. J. Farnell, S. E. Krueger +3
In this article, we present new results of high-order coupled cluster method (CCM) calculations, based on a Néel model state with spins aligned in the -direction, for both the g…
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…
Simulation of the Zero Temperature Behavior of a 3-Dimensional Elastic Medium
David McNamara, A. Alan Middleton, Chen Zeng
We have performed numerical simulation of a 3-dimensional elastic medium, with scalar displacements, subject to quenched disorder. We applied an efficient combinatorial optimizatio…
