Comment on "Anomalous Reentrant 5/2 Quantum Hall Phase at Moderate Landau-Level-Mixing Strength''

Abstract

Das, Das, and Mandal (PRL 131, 056202, 2023) examine a wavefunction for nu = 5/2 on a sphere including moderate Landau-Level mixing evaluated perturbatively. The wavefunction they find is not a fractional quantum Hall (FQH) state as claimed, but rather shows phase separation or bubble/stripe formation.
