Disorder-driven phase transitions in bosonic fractional quantum Hall liquids
Disorder-driven phase transitions in bosonic fractional quantum Hall liquids
We investigate the disorder-driven phase transitions in bosonic fractional quantum Hall liquids at filling factors $f=1/2$ and $f=1$ in the lowest Landau level. We use the evolution of ground-state entanglement entropy, fidelity susceptibility, and Hall conductance with increasing disorder strength to identify the underlying phase transitions. The critical disorder strengths …
