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…

Crossover from Integer to Fractional Quantum Hall Effect

Koji Kudo, Jonathan Schirmer, Jainendra K. Jain

The parton theory constructs candidate fractional quantum Hall states by decomposing the physical particles into unphysical partons, placing the partons in integer quantum Hall sta…
