Characterization of quasiholes in two-component fractional quantum Hall states and fractional Chern insulators in $|C|=2$ flat bands

Błażej Jaworowski, Nicolas Regnault, Zhao Liu

We perform an exact-diagonalization study of quasihole excitations for the two-component Halperin $(221)$ state in the lowest Landau level and for several $\nu =1/3$ bosonic fractiona…
