Thermodynamics of Mesoscopic Vortex Systems in 1+1 Dimensions
arXiv:cond-mat/9909193 · doi:10.1103/PhysRevLett.83.4860
Abstract
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, the anomalous vortex displacement is found to agree well with the prediction of the renormalization-group theory. Interesting behaviors such as the universal statistics of magnetic susceptibility variations are observed in both the dense and dilute regimes of this mesoscopic vortex system.
