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…
Imaging of high-frequency electromagnetic field by multipulse sensing using nitrogen vacancy centers in diamond
Shintaro Nomura, Hideyuki Watanabe, Satoshi Kashiwaya
Near-field enhancement of the microwave field is applied for imaging high frequency radio field using a diamond chip with an -doped isotopically purified diamond layer grown by…
Angle dependence of N nuclear spin dynamics in diamond NV centers
Yusuke Azuma, Shintaro Nomura, Hideyuki Watanabe +1
We report on the dynamics of the Rabi oscillation and the Larmor precession of N nuclear spin using nonselective short microwave pulses for initialization of N nuclea…
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…
