Scalar-spin-chirality-driven fractional Chern insulator on a kagome lattice
Shinnosuke Tsutsumi, Koji Kudo, Kentaro Nomura
The paper shows that a kagome lattice with noncoplanar magnetic order and finite scalar spin chirality can host fractional Chern insulator states, especially when electron-electron…
Repulsive-Interaction-Driven Topological Superconductivity in a Landau Level Coupled to an -Wave Superconductor
Koji Kudo, Ryota Nakai, Hiroki Isobe +2
A two-dimensional topologically nontrivial state of noninteracting electrons, such as the surface state of a three-dimensional topological insulator, is predicted to realize a topo…
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…
Quantum anomalous, spin, and valley Hall effects in pentalayer rhombohedral graphene moiré superlattices
Koji Kudo, Ryota Nakai, Kentaro Nomura
Recent experiments on pentalayer rhombohedral graphene moiré superlattices have observed the quantum anomalous Hall effect at moiré filling factor of and various fraction…
