Hierarchical structure of primary and hybridization-induced superconducting correlations in bilayer nickelates
Hiroshi Watanabe, Hirofumi Sakakibara, Kazuhiko Kuroki
High-pressure superconductivity in the bilayer nickelate LaNiO, with a transition temperature approaching 80 K, has stimulated intense debate regarding its microscopic…
Theoretical proposal of superconductivity in hole-doped reduced bilayer nickelate La3Ni2O6: a manifestation of orbital-space bilayer model with incipient bands
Shu Kamiyama, Reo Kohno, Yuto Hoshi +4
A correspondence exists between the multi-orbital Hubbard model and the bilayer Hubbard model, in which superconductivity is optimized in an incipient-band regime in both cases. In…
Spin-fluctuation-mediated chiral -wave superconductivity in the - lattice with an incipient flat band
Masataka Kakoi, Kazuhiko Kuroki
We study anisotropic superconductivity in the nearly quarter-filled - lattice. We analyze an extended Hubbard model with off-site attractive interactions within t…
Josephson effect in quasi one-dimensional unconventional superconductors
Y. Asano, Y. Tanaka, Y. Tanuma +2
Josephson effect in junctions of quasi one-dimensional triangular lattice superconductors is discussed, where the theoretical model corresponds to organic superconductors (TMTSF)_2…
Electronic Structure of B-2 and States in MgB, AlB and ZrB Single Crystals
J. Nakamura, S. Nasubida, E. Kabasawa +18
The effect of electron correlation (EC) on the electronic structure in MgB, AlB and ZrB, is studied by examining the partial density of states (PDOS) of B-2 and $pπ…
