Solitons and Their Arrays: from Quasi One-Dimensional Conductors to Stripes

TL;DR

This paper reviews solitonic lattices in quasi-one-dimensional conductors, discusses their relevance to stripe phases, and interprets recent experimental observations, proposing a theory for soliton-based ordered phases and their complex topological configurations.

Contribution

It provides a comprehensive review of solitons in low-dimensional conductors and introduces a theoretical framework for their complex topological forms in relation to experimental findings.

Findings

Solitons are fundamental excitations in organic conductors and charge density waves.

Ordered phases involve solitons forming combined topological structures like kink-roton complexes.

Recent STM observations of local rod-like structures in cuprates can be interpreted through soliton theory.

Abstract

We suggest a short review of literature on various solitonic lattices and individual solitons in quasi one-dimensional conductors. This information seems to be quite relevant to topics of stripes and their melted phases correspondingly. We shall quote also the latest experiments, which access solitons as elementary excitations in organic conductors and in charge density waves. We shall outline a theory for ordered phases, where solitons should acquire forms of combined topological configurations (kink-roton complexes). The extension of this picture to cuprates allows interpretation the latest STM observations on local rod-like structures.
