Field resilient superconductivity in atomic layer crystalline materials
Yoichi Higashi, Shunsuke Yoshizawa, Takashi Yanagisawa +3
A recent study [S. Yoshizawa {\it et al}., Nature Communications {\bf 12}, 1462 (2021)] reported the occurrence of field-resilient superconductivity, that is, enhancement of the in…
Round-Core-Radius-Dependent Electromagnetic Coupling of Multifilament Helical Superconducting Tapes in a Swept Magnetic Field
Yoichi Higashi, Yasunori Mawatari
With the excitation and demagnetization of a magnet for magnetic resonance imaging in mind, we theoretically and numerically investigated electromagnetic coupling--especially its d…
Efficient Numerical Modeling of the Magnetization Loss on a Helically Wound Superconducting Tape in a Ramped Magnetic Field
Yoichi Higashi, Yasunori Mawatari
We investigate theoretically the dependence of magnetization loss of a helically wound superconducting tape on the round core radius and the helical conductor pitch in a ramped…
Fractional skyrmion and absence of low-lying Andreev bound states in a micro fractional-flux quantum vortex
Takashi Yanagisawa, Yoichi Higashi, Izumi Hase
We investigate quasi-particle excitation modes and the topological number of a fractional-flux quantum vortex in a layered (multi-component) superconductor. The Bogoliubov equation…
Analysis of Magnetization Loss on a Twisted Superconducting Strip in a Constantly Ramped Magnetic Field
Yoichi Higashi, Huiming Zhang, Yasunori Mawatari
Magnetization loss on a twisted superconducting (SC) tape in a ramped magnetic field is theoretically investigated through the use of a power law for the electric field--current de…
Electromagnetic coupling of twisted multi-filament superconducting tapes in a ramped magnetic field
Yoichi Higashi, Yasunori Mawatari
We investigate theoretically the magnetization loss and electromagnetic coupling of twisted multi-filament superconducting (SC) tapes in a ramped magnetic field. Based on the two-d…
