Solid State Analog for He-McKellar-Wilkens Quantum Phase

TL;DR

This paper demonstrates that a charged quasiparticle in a solid state system exhibits a topological quantum phase analogous to the He-McKellar-Wilkens effect, induced by a screw dislocation and a magnetic field.

Contribution

It introduces a solid state analog of the He-McKellar-Wilkens quantum phase through analysis of quasiparticle dynamics in a dislocated crystal with magnetic field.

Findings

Observation of a topological quantum phase in a solid state system.

Demonstration of the solid state analog of the He-McKellar-Wilkens effect.

Abstract

In this letter we investigate the quantum dynamics of a quasiparticle in the presence of a charged screw dislocation submitted to a uniform magnetic field. Analysing the quantum scattering for this quasiparticle we observed the appearance of a topological quantum phase in the solution and demonstrate that this phenomenon is the solid state analog of the He-McKeller-Wilkens effect.
