Quasiparticles in quantum Hall effect: Smet's fractional charge

TL;DR

This paper presents a new formula predicting fractional charges of quasiparticles in the quantum Hall effect, aligning well with experimental observations and revealing a relationship between spin and charge.

Contribution

The paper introduces a novel formula that accurately predicts fractional charges and uncovers a link between spin and charge of quasiparticles in the quantum Hall effect.

Findings

The formula predicts fractional charges consistent with experimental data.

A relationship between spin and charge of quasiparticles is established.

The approach resolves discrepancies in previous models.

Abstract

It has been pointed out by Smet that there are fractional-charge values which do not fit with their formula of composite fermions. We find that our formula predicts these fractional charges very well and in fact there exists a relationship between spin and charge of a quasiparticle.
