Title: Thermal Conductance of the nu=5/2 Fractional Quantum Hall State
Abstract: Recent tour-de-force experiments (Banerjee, Heiblum, et al,
Nature 2018) have measured the thermal conductance of the nu=5/2 edge in
a GaAs electron gas and found it to be quantized as approximately K=5/2
(in appropriate dimensionless units). This result is unexpected, as
prior numerical work predicts that the nu=5/2 state should be the
Anti-Pfaffian phase of matter, which would give K=3/2, or the possibly
the Moore-Read Pfaffian which would give K=7/2. I will discuss and
evaluate several possible explanations of the experimental result.
