Phi_0 - Periodic Aharonov-Bohm Oscillations Survive Ensemble Averaging

TL;DR

This paper shows that Phi_0 periodic Aharonov-Bohm oscillations can persist after ensemble averaging, highlighting their robustness under realistic experimental conditions such as finite temperature and charging energy.

Contribution

It demonstrates the survival of Aharonov-Bohm oscillations after ensemble averaging, contrasting with previous assumptions that they would average out.

Findings

Aharonov-Bohm oscillations can survive ensemble averaging.

Oscillations are robust at finite temperature.

Effect persists despite non-zero charging energy.

Abstract

We have demonstrated that Phi_0 periodic Aharonov--Bohm oscillations measured in a ensemble of rings may survive after ensemble averaging procedure. The central point is the difference between the preparation stage of the ensemble and the subsequent measurement stage. The robustness of the effect under finite temperature and non--zero charging energy of rings is discussed.
