Scalar-spin-chirality-driven fractional Chern insulator on a kagome lattice
Shinnosuke Tsutsumi, Koji Kudo, Kentaro Nomura
Fractional Chern insulators (FCIs) are the lattice analogs of the fractional quantum Hall states, emerging even without an external magnetic field. In this work, we demonstrate the…

Topological superconductivity on a kagome magnet coupled to a Rashba superconductor
Koji Kudo, Ryota Nakai, Hiroki Isobe +1
A quantum anomalous Hall system is predicted to realize topological superconductivity when proximity-coupled to an -wave superconductor. A kagome magnet with chiral magnetic ord…

Chirality-selective proximity effect between chiral -wave superconductors and quantum Hall insulators
Ryota Nakai, Koji Kudo, Hiroki Isobe +1
Heterostructures of superconductors and quantum-Hall insulators are promising platforms of topological quantum computation. However, these two systems are incompatible in some aspe…
