Two-Dimensional Anharmonic Crystal Lattices: Solitons, Solectrons, and Electric Conduction

TL;DR

This paper explores how solitons in anharmonic 2D crystal lattices facilitate novel electron transport mechanisms, including solectrons and ballistic conduction, with implications for electron pairing and percolation.

Contribution

It introduces the concept of electron-soliton bound states (solectrons) and discusses their role in electron transport and pairing in 2D anharmonic lattices.

Findings

Electron-soliton bound states (solectrons) can form in anharmonic lattices.

Soliton-mediated transport enables ballistic conduction and electron surfing.

Potential for percolation and novel electron pairing mechanisms in 2D lattices.

Abstract

Reported here are salient features of soliton-mediated electron transport in anharmonic crystal lattices.After recalling how an electron-soliton bound state (solectron) can be formed we comment on consequences like electron surfing on a sound wave and balistic transport, possible percolation in 2d lattices, and a novel form of electron pairing with strongly correlated electrons both in real space and momentum space.
