Anyon exciton revisited

TL;DR

This paper reviews the anyon exciton model, addressing recent criticisms by analyzing finite-size effects in spherical geometry, and clarifies the nature of fractionally charged anyon ions in excitation spectra.

Contribution

It clarifies that the appearance of fractionally charged anyon ions is an artifact of finite-size effects, revisiting the theoretical model in light of recent critiques.

Findings

Fractionally charged anyon ions are artifacts of finite-size effects.

The paper revisits the exciton model in light of recent criticism.

Finite-size effects influence the interpretation of excitation spectra.

Abstract

We review the main results of the anyon exciton model in light of recent criticism by Wojs and Quinn. We show that the appearance of fractionally charged anyon ions at the bottom of their numerically calculated excitation spectra is an artefact caused by finite-size effects in a spherical geometry.
