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…
Conductance Anomaly and Fano Factor Reduction in Quantum Point Contacts
Shuji Nakamura, Masayuki Hashisaka, Yoshiaki Yamauchi +3
We report an experimental study on the shot noise as well as the dc transport properties of a quantum point contact (QPC) whose conductance anomaly can be tuned electrostatically b…
