Radiation-Induced Zero-Resistance State at Low Magnetic Fields and near Half Filling of the Lowest Landau Level

TL;DR

This paper predicts a radiation-induced zero-resistance state near half filling of the lowest Landau level, caused by photon-assisted transport and composite fermion Landau levels, extending understanding of quantum Hall effects under radiation.

Contribution

It introduces a non-perturbative theoretical prediction of zero-resistance states near half filling, emphasizing the role of composite fermions and radiation without dependence on radiation power or frequency.

Findings

Zero-resistance state predicted near half filling of lowest Landau level

State caused by photon-assisted transport in composite fermion Landau levels

Prediction independent of radiation power and frequency

Abstract

We theoretically predict the radiation-induced ``zero-resistance state'' near half filling of the lowest Landau level, which is caused by the photon-assisted transport in the presence of oscillating density of states due to composite fermion Landau levels, and is analogous to the radiation-induced ``zero-resistance state'' of electrons at low magnetic fields. Based on a non-perturbative theory, we show that the radiation field does not break the bound state of electrons and flux quanta, i.e. composite fermions. Our prediction is independent of the power and frequency of radiation field.
