Dynamic scaling of I-V data for the neutral 2D Coulomb gas

TL;DR

This paper investigates the dynamic critical exponent z in 2D Coulomb gas systems, combining experimental and simulation data to reveal non-diffusive dynamics characterized by a large z value around 5.6.

Contribution

It extends previous experimental findings by confirming the large z value through simulation of I-V curves in the 2D Coulomb gas, highlighting non-diffusive dynamics.

Findings

z approximately 5.6 in both experimental and simulated data

Large z indicates non-diffusive dynamics in 2D Coulomb gas

Consistent dynamic scaling behavior across experiments and simulations

Abstract

The value of the dynamic critical exponent z has been studied for experimental two-dimensional superconducting and Josephson Junction array systems in zero magnetic field via the Fisher-Fisher-Huse dynamic scaling analysis. We found z~5.6, a relatively large value indicative of non-diffusive dynamics. We extend this work here to simulational I-V curves that are also found to be characterized by the same large value of z.
