Journal ArticleDOI
Quantum coherence in quantum dot—Aharonov–Bohm ring hybrid systems
TL;DR: In this article, the Fano effect was applied to detect electrostatic phase modulation and phase shift in a quantum wire with a side-coupled dot and provided an experimental answer to the problem of neighboring in-phase Coulomb peaks.
Journal ArticleDOI
Magnetization reversal in a ferromagnetic circular dot under current induced resonant excitation
TL;DR: In this paper, the magnetic properties of a ferromagnetic circular dot in its dynamical state with a vortex core on resonance as well as off resonance were studied, and it was shown that the annihilation field of the vortex core is reduced in the resonance state compared to the off-resonance state.
Journal ArticleDOI

TL;DR: In this article, a clear Shubnikov-de-Haas oscillation was observed in the whole temperature range and the temperature dependence of the oscillation amplitude was found to deviate from the Lifshitz-Kosevich formula below the magnetic transition temperature at TN 1 ≈ 3 K. This indicates a significant interplay between the magnetic ordering and the conduction electrons, which could lead to a modification of the effective cyclotron mass.

TL;DR: In this paper, a clear Shubnikov-de-Haas (SdH) oscillation was observed at 4'K, demonstrating the strong two-dimensional nature in this material.
Journal ArticleDOI
Work fluctuation theorem for a classical circuit coupled to a quantum conductor
TL;DR: In this paper, the authors propose a setup for a quantitative test of the quantum fluctuation theorem, which consists of a quantum conductor driven by an external voltage source, and a classical inductor-capacitor circuit.
