Shot Noise Induced by Electron-nuclear Spin-flip Scattering in a Nonequilibrium Quantum Wire
Kensaku Chida, Masayuki Hashisaka, Yoshiaki Yamauchi +5
We study the shot noise (nonequilibrium current fluctuation) associated with dynamic nuclear polarization in a nonequilibrium quantum wire (QW) fabricated in a two-dimensional elec…
Evolution of the Kondo Effect in a Quantum Dot Probed by the Shot Noise
Yoshiaki Yamauchi, Koji Sekiguchi, Kensaku Chida +6
We measure the current and shot noise in a quantum dot (QD) in the Kondo regime to address the non-equilibrium properties of the Kondo effect. By systematically tuning the temperat…
Fluctuation Theorem and Microreversibility in a Quantum Coherent Conductor
Shuji Nakamura, Yoshiaki Yamauchi, Masayuki Hashisaka +8
Mesoscopic systems provide us a unique experimental stage to address non-equilibrium quantum statistical physics. By using a simple tunneling model, we describe the electron exchan…
Temperature dependence of the visibility in an electronic Mach-Zehnder interferometer
Masayuki Hashisaka, Andreas Helzel, Shuji Nakamura +7
We performed the conductance and the shot noise measurements in an electronic Mach-Zehnder interferometer. The visibility of the interference is investigated as a function of the e…
Non-equilibrium Fluctuation Relations in a Quantum Coherent Conductor
Shuji Nakamura, Yoshiaki Yamauchi, Masayuki Hashisaka +8
We experimentally demonstrate the validity of non-equilibrium fluctuation relations by using a quantum coherent conductor. In equilibrium the fluctuation-dissipation relation leads…
Universality of Bias- and Temperature-induced Dephasing in Ballistic Electronic Interferometers
Y. Yamauchi, M. Hashisaka, S. Nakamura +8
We performed a transport measurement in a ballistic Aharonov-Bohm ring and a Fabry-Perot type interferometer. In both cases we found that the interference signal is reversed at a c…
