I.L. Aleiner, A. V. Andreev, and V. Vinokur
TL;DR
This paper demonstrates that singly-connected disordered conductors exhibit quantum Aharonov-Bohm oscillations in their transport and thermodynamic properties, due to interference effects from specific electron trajectories on the sample surface.
Contribution
It reveals the presence of Aharonov-Bohm oscillations in singly-connected disordered conductors, highlighting a novel interference mechanism involving surface-confined electron trajectories.
Findings
Observation of quantum Aharonov-Bohm oscillations in disordered conductors
Identification of surface-confined electron trajectories as the interference source
Connection between magnetic flux and oscillation behavior
Abstract
We show that transport and thermodynamic properties of \emph{singly-connected} disordered conductors exhibit quantum Aharonov - Bohm oscillations with the total magnetic flux through the system. The oscillations are associated with the interference contribution from a special class of electron trajectories confined to the surface of the sample.
