Superconductivity on a Möbius strip: numerical studies on order parameter and quasiparticles
Masahiko Hayashi, Hiromichi Ebisawa, Kazuhiro Kuboki
Superconducting states of an anisortopic s-wave superconductor on a Möbius strip are studied numerically based on the Ginzburg-Landau theory and the Bogoliubov-de Gennes theory. In…
Little-Parks Oscillation of Superconducting Möbius Strip
Masahiko Hayashi, Hiromichi Ebisawa
Little-Parks oscillation of a Möbius strip (or ring equivalently) made of a superconductor is studied based on Ginzburg-Landau theory. It is shown that, if the strip is wide enough…
Cooper Pair Formation in U(1) Gauge Theory of High Temperature Superconductivity
Atsuya Kumagai, Masahiko Hayashi, Hiromichi Ebisawa
We study the two-dimensional spin-charge separated Ginzburg-Landau theory containing U(1) gauge interactions as a semi-phenomenological model describing fluctuating condensates in…
Spectral Flow and Quantum Theory of Dissipation in the Vortex Core of BCS superconductors
Masahiko Hayashi
The dissipation process in two dimensional BCS superconductor due to the quasiparticles in the core of moving vortex is studied from a quantum mechanical point of view, especially…
