Phase Diagram of the 5/2 Fractional Quantum Hall State in Presence of Landau Level Mixing Revisited

ORAL

Abstract

We revisit the quantum phase diagram of the 5/2 fractional quantum Hall state in semiconductor quantum wells at finite magnetic field and finite width of the 2D electron gas. The model includes higher 3-body pseudopotentials that were shown (PRL 119, 026801 (2017)) to be important for the Pfaffian versus anti-Pfaffian competition. We identify the ground state throughout the phase diagram by examining the energetic and entanglement properties by means of exact diagonalisation.
