Aharonov-Bohm oscillations beating and universal conductance fluctuations in a single-mode quantum interferometer

This paper presents the results of the study of the beating of Aharonov-Bohm oscillations and universal conductance fluctuations in an electron ring interferometer fabricated on the basis of a 2D electron gas in AlGaAs/GaAs heterostructure. It is shown that the behavior of both the beating and universal conductance fluctuations is determined by the width of the conducting channels of an interferometer.
