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…
Phase Separation Induced by Density-Dependent Hopping Terms
Kazuhiro Kuboki
We study phase separation in the model in which the constraint of no double occupancy due to strong electron correlations leads to effective narrowing of the band width. U…
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…
Static spin susceptibility in magnetically ordered states
Kazuhiro Kuboki, Hiroyuki Yamase
We report that special care is needed when longitudinal magnetic susceptibility is computed in a magnetically ordered phase, especially in metals. We demonstrate this by studying s…
