Phase Separation in Kitaev Chain
Kazuhiro Kuboki
Kitaev chain is a one-dimensional spinless fermion model that has -wave superconducting (SC) states and Majorana zero modes at the edge. Usually this model is analyzed by taking…
Spontaneous Magnetic Field and Local Density of States near a Time-Reversal Symmetry Broken Surface State of YBCO
Kazuhiro Kuboki
We study theoretically the spatial distribution of spontaneous magnetic fields near a (110) surface of cuprate high- superconductor YBCO by treating a bilayer model with…
Spontaneous Magnetic Field near a Time-Reversal Symmetry Broken Surface State of YBCO
Kazuhiro Kuboki
Spatial distributions of spontaneous magnetic fields near a surface of cuprate high- superconductor YBCO with broken time-reversal symmetry are calculated using the Ginzburg-L…
Ginzburg-Landau Theory for Flux Phase and Superconductivity in Model
Kazuhiro Kuboki
Ginzburg-Landau (GL) equations and GL free energy for flux phase and superconductivity are derived microscopically from the model on a square lattice. Order parameter (OP) fo…
Flux Phase in Bilayer Model: Time-Reversal Symmetry Breaking Surface State without Spontaneous Magnetic Field
Kazuhiro Kuboki
We study surface states of high- cuprate superconductor YBCO using the bilayer model. Calculations based on the Bogoliubov de Gennes method show that a flux phase that b…
Flux Phase in Bilayer Model
Kazuhiro Kuboki
In order to study the time-reversal symmetry () breaking near a (110) surface of a high- cuprate YBCO, we consider the flux phase in a bilayer model. Although…
