Evaluation of Doppler shifts in -wave superconductor tunneling junctions
Takashi Sakamori, Kenki Matsuoka, Mitsuhiro Teshigawara +4
The energy levels of quasiparticles in superconductors experience Doppler shifts due to the influence of a finite current flow. The influence of the Doppler shift is particularly p…
Theory of Josephson current on a lattice model of grain boundary in -wave superconductors
Takashi Sakamori, Satoshi Kashiwaya, Rikizo Yano +3
Identifying the origins of suppression of the critical current at grain boundaries of high-critical-temperature superconductors, such as cuprates and iron-based superconductors, is…
Identification of Spin-Triplet Superconductivity through a Helical-Chiral Phase Transition in SrRuO Thin-Films
S. Ikegaya, K. Yada, Y. Tanaka +3
Despite much effort for over the two decades, the paring symmetry of a SrRuO superconductor has been still unclear. In this Rapid Communication, motivated by the recent rap…
Time-Reversal Invariant Superconductivity of SrRuO Revealed by Josephson Effects
Satoshi Kashiwaya, Kohta Saitoh, Hiromi Kashiwaya +5
SrRuO is one of the most promising candidates of a topological superconductor with broken time-reversal symmetry, because a number of experiments have revealed evidence…
Local impedance on a rough surface of a chiral -wave superconductor
S. V. Bakurskiy, Ya. V. Fominov, A. F. Shevchun +8
We develop a self-consistent approach for calculating the local impedance at a rough surface of a chiral -wave superconductor. Using the quasiclassical Eilenberger-Larkin-Ovchin…
Unusual Superconducting Proximity Effect in Magnetically Doped Topological Josephson Junctions
Rikizo Yano, Masao Koyanagi, Hiromi Kashiwaya +5
The transport properties of a topological Josephson junction fabricated from a magnetically doped topological insulator (TI) were investigated. The conductance spectra of the Nb/Fe…
