Theory of proximity effect in normal metal/-wave superconductor interface in the presence of subdominant components of the pair potentials
Y. Tanuma, Y. Tanaka, S. Kashiwaya
Superconducting proximity effect in normal metal (N) / -wave superconductor (D) junctions in the presence of attractive interelectron potentials which can induce subdo…
Nature of carriers in one-dimensional correlated electron systems
Hiroki Tsuchiura, Masao Ogata, Yukio Tanaka +1
Electron densities at the edge site in one-dimensional Hubbard model and t-J model are studied by using the Bethe ansatz solutions and exact diagonalization method. It is found tha…
Split of zero-bias conductance peak in normal-metal / d-wave superconductor junctions
Y. Yasano, Y. Tanaka, S. Kashiwaya
Effects of impurity scatterings on the conductance in normal-metal / wave superconductor junctions are discussed by using the single-site approximation. So far, the split of th…
Theory of the Josephson effect in superconductor / ferromagnet / superconductor junctions
Y. Tanaka, S. Kashiwaya
To reveal the influence of the exchange interaction on the Josephson effect, the d.c. Josephson current in unconventional-superconductor / ferromagnet / unconventional-superconduct…
Theoretical study of the Josephson current through a junction including ferromagnetic insulator
Masashi Yamashiro, Nobukatsu Yoshida, Yukio Tanaka +1
The properties of Josephson junction including a ferromagnetic insulating layer are studied theoretically. The calculated current shows the anomalous dependence on the magnitude of…
