Orbital Order in Two-orbital Hubbard Model
Kojiro Honkawa, Seiichiro Onari
In strongly correlated multi-orbital systems, various ordered phases appear. In particular, the orbital order in iron-based superconductors attracts much attention since it is cons…
Pair-breaking of multi-gap superconductivity under parallel magnetic fields in electric-field-induced surface metallic state
Masahiro Nabeta, Kenta K. Tanaka, Seiichiro Onari +1
Roles of paramagnetic and diamagnetic pair-breaking effects in superconductivity in electric-field-induced surface metallic state are studied by Bogoliubov-de Gennes equation, when…
Spin-polarized local density of states in the vortex state of helical p-wave superconductors
Kenta K. Tanaka, Masanori Ichioka, Seiichiro Onari
Properties of the vortex state in helical p-wave superconductor are studied by the quasi-classical Eilenberger theory. We confirm the instability of the helical p-wave state at hig…
