Coexistence of superconductivity and charge-density wave in the quasi-one-dimensional material HfTe3
Saleem J. Denholme, Akinori Yukawa, Kohei Tsumura +6
We present the first experimental evidence for metallicity, superconductivity (SC) and the co-existence of charge density waves (CDW) in the quasi-one-dimensional material HfTe3. T…
Carrier flow and nonequilibrium superconductivity in superconductor-based light-emitting diode
Ryotaro Inoue, Hideaki Takayanagi, Tatsushi Akazaki +3
Superconductor-based light-emitting diode (superconductor-based LED) in strong light-confinement regime are characterized as a superconductor-based three-terminal device, and its t…
Transport properties of Andreev polarons in superconductor-semiconductor-superconductor junction with superlattice structure
Ryotaro Inoue, Kenta Muranaga, Hideaki Takayanagi +4
Transport properties of a superconductor-semiconductor-superconductor (S-Sm-S) junction with superlattice structure are investigated. Differential resistance as a function of volta…
Luminescence of a Cooper Pair
Yasuhiro Asano, Ikuo Suemune, Hideaki Takayanagi +1
This paper theoretically discusses the photon emission spectra of a superconducting pn-junction. On the basis of the second order perturbation theory for electron-photon interactio…
Tunnelling spectroscopy of the interface between Sr2RuO4 and a single Ru micro-inclusion in eutectic crystals
Hiroshi Yaguchi, Keiichi Takizawa, Minoru Kawamura +6
The understanding of the zero bias conductance peak (ZBCP) in the tunnelling spectra of S/N junctions involving d-wave cuprate superconductors has been important in the determinati…

Tunneling properties at the interface between superconducting Sr2RuO4 and a Ru micro-inclusion
M. Kawamura, H. Yaguchi, N. Kikugawa +2
We have investigated the magnetic field and temperature dependence of the tunneling spectra of the eutectic system Sr2RuO4-Ru. Electric contacts to individual Ru lamellae embedded…
A theoretical analysis of flux-qubit measurements with a dc-SQUID
H. Nakano, H. Tanaka, S. Saito +3
The readout process of a superconducting flux-qubit is theoretically analyzed in terms of the quantum dynamics of a qubit-SQUID coupled system during measurement. The quantity dire…
DC-SQUID Sensitivity for Readout of Entangled State Quantum Bits
H. Tanaka, Y. Sekine, S. Saito +1
We propose a scheme for entangled state measurement at flux qubits (quantum bits) depending on the sensitivity measurement of a DC-SQUID (Superconducting QUantum Interference Devic…
Josephson effects in a superconductor-normal metal mesoscopic structure with a dangling superconducting arm
R. Shaikhaidarov, A. F. Volkov, H. Takayanagi +2
We studied a mesoscopic cross-like normal metal structure connected to two superconducting (S) and two normal (N) reservoirs. We observed the Josephson effect under unusual conditi…
