Dynamical Transverse Meissner Effect and Transition in Moving Bose Glass

TL;DR

This paper investigates the behavior of moving periodic structures in disordered systems, revealing a transition between two glass phases characterized by the presence or absence of the transverse Meissner effect, with implications for vortex lattices and CDWs.

Contribution

It introduces a renormalisation group analysis showing the persistence of disorder effects at all velocities and predicts a sharp transition between two distinct moving glass phases.

Findings

Disorder effects persist at all velocities in a Moving Bose Glass phase.

A sharp transition occurs at a critical velocity between two moving glass phases.

The transverse Meissner effect is present in one phase and absent in the other.

Abstract

We study moving periodic structures in presence of correlated disorder using renormalisation group. We find that the effect of disorder persists at all velocities resulting at zero temperature in a Moving Bose Glass phase with transverse pinning. At non zero temperature we find two distinct moving glass phases. We predict a sharp transition, as velocity increases between the Moving Bose Glass, where the transverse Meissner effect persists in the direction transverse to motion and a Correlated Moving Glass at high velocity, where it disappears. Experimental consequences for vortex lattices and charge density wave (CDW) systems are discussed.
