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…
Universal Transport Theory for Paired Fractional Quantum Hall States in the Quantum Point Contact Geometry
Eslam Ahmed, Ryoi Ohashi, Hiroki Isobe +2
Even-denominator fractional quantum Hall (FQH) states can be viewed as topological superconductors of composite fermions, supporting a charged chiral mode and …
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…
