Depinning and plasticity of driven disordered lattices

TL;DR

This paper reviews the dynamics of driven disordered lattices in condensed matter systems, emphasizing the effects of strong disorder, topological defects, and plastic response on depinning transitions.

Contribution

It provides a comprehensive review of how strong disorder influences the depinning and plasticity in driven lattices, highlighting the role of topological defects and hysteresis.

Findings

Plastic response occurs in strongly disordered driven lattices.

Depinning transition can be discontinuous and hysteretic under strong disorder.

Topological defects are generated during the driven dynamics.

Abstract

We review in these notes the dynamics of extended condensed matter systesm, such as vortex lattices in type-II superconductors and charge density waves in anisotropic metals, driven over quenched disorder. We focus in particular on the case of strong disorder, where topological defects are generated in the driven lattice. In this case the repsonse is plastic and the depinning transition may become discontinuous and hysteretic.
