Manabu Machida, Naomichi Hatano, and Jun Goryo
TL;DR
This paper investigates the nonadiabatic effects on conductances in the quantum Hall effect of Bloch electrons, revealing large-frequency oscillations caused by quantum fluctuations.
Contribution
It introduces the study of nonadiabatic effects and quantum fluctuations on conductance oscillations in the quantum Hall regime of Bloch electrons.
Findings
Hall and longitudinal conductances oscillate in time.
Oscillation frequencies are very large.
Quantum fluctuations drive the oscillations.
Abstract
We study a nonadiabatic effect on the conductances in the quantum Hall effect of two-dimensional electrons with a periodic potential. We found that the Hall and longitudinal conductances oscillate in time with a very large frequencies due to quantum fluctuation.
