Interaction-driven transition between the Wigner crystal and the fractional Chern insulator in topological flat bands
Michał Kupczyński, Błażej Jaworowski, Arkadiusz Wójs
We investigate an interaction-driven transition between crystalline and liquid states of strongly correlated spinless fermions within topological flat bands at low density (with fi…
Model wavefunctions for an interface between lattice Laughlin and Moore-Read states
Błażej Jaworowski, Anne E. B. Nielsen
We use conformal field theory to construct model wavefunctions for a gapless interface between lattice versions of a bosonic Laughlin state and a fermionic Moore-Read state, both a…
Model wavefunctions for interfaces between lattice Laughlin states
Błażej Jaworowski, Anne E. B. Nielsen
We study the interfaces between lattice Laughlin states at different fillings. We propose a class of model wavefunctions for such systems constructed using conformal field theory.…
Characterization of quasiholes in two-component fractional quantum Hall states and fractional Chern insulators in flat bands
Błażej Jaworowski, Nicolas Regnault, Zhao Liu
We perform an exact-diagonalization study of quasihole excitations for the two-component Halperin state in the lowest Landau level and for several bosonic fractiona…
