Direct Numerical Confirmation of Pinning Induced Sign Change in Superconducting Hall Effect in Type-II Superconductors
N. Nakai, N. Hayashi, M. Machida
Using the time-dependent Ginzburg-Landau equation with the complex relaxation time and the Maxwell equation, we systematically examine transverse motion of vortex dynamics in the p…
Effect of Fermi Surface Topology on Inter-Layer Magnetoresistance in Layered Multiband Systems: Application to LaFeAsO1-xFx
Takao Morinari, Hiroki Nakamura, Masahiko Machida +1
In layered single band systems, the interlayer conductivity depends on the orientation of the in-plane magnetic field and takes maximum values when the magnetic field is perpendicu…
Intergrain Josephson Currents in Multigap Superconductors: Microscopic Origin of Low Intergrain Critical Current and Its Recovery Potential in Iron-Pnictide Materials
Yukihiro Ota, Masahiko Machida, Tomio Koyama
We microscopically examine the intergrain Josephson current in iron-pnictide superconductors in order to solve the puzzle of why the intergrain current is much lower than the intra…
Theory of heterotic SIS Josephson junctions between single- and multi-gap superconductors
Yukihiro Ota, Masahiko Machida, Tomio Koyama +1
Using the functional integral method, we construct a theory of heterotic SIS Josephson junctions between single- and two-gap superconductors. The theory predicts the presence of in…
