TL;DR

This study uses large-scale simulations to explore the dynamic and static behaviors of randomly pinned flux lines in a plane, revealing a vortex glass transition with less glassiness than anticipated and no static signatures of the transition.

Contribution

It provides new insights into the vortex glass transition in a planar flux array, highlighting discrepancies between dynamic and static properties.

Findings

Vortex glass transition identified at expected temperature

Vortex glass phase is less glassy than predicted

No static signatures of the glass transition detected

Abstract

We report the results of large scale numerical studies of the dynamic and static properties of the random phase model of the randomly pinned flux lines confined in a plane. From the onset of nonlinear IV characteristics, we identify a vortex glass transition at the theoretically anticipated temperature. However, the vortex glass phase itself is much {\it less glassy} than expected. No signature of the glass transition has been detected in the static quantities measured.
