Resistivity peak values at transition between fractional quantum Hall states

TL;DR

This paper compares experimental peak resistivity values at fractional quantum Hall transitions with theoretical predictions, finding close agreement for systems with moderate mobilities.

Contribution

It provides a systematic comparison between experimental data and theoretical models for resistivity peaks in fractional quantum Hall transitions.

Findings

Most experimental peak values align with theoretical predictions.

Agreement is particularly strong for systems with moderate mobilities.

Results support the validity of current theoretical models in these conditions.

Abstract

Experimental data available in the literature for peak values of the diagonal resistivity in the transitions between fractional quantum Hall states are compared with the theoretical predictions. It is found that the majority of the peak values are close to the theoretical values for two-dimensional systems with moderate mobilities.
