Partial equilibration of the anti-Pfaffian edge due to Majorana Disorder
We consider electrical and thermal equilibration of the edge modes of the Anti-Pfaffian quantum Hall state at ν = 5/2 due to tunneling of the Majorana edge mode to trapped Majorana zero modes in the bulk. Such tunneling breaks translational invariance and allows scattering between Majorana and other...

| Özet: | We consider electrical and thermal equilibration of the edge modes of the Anti-Pfaffian quantum
Hall state at ν = 5/2 due to tunneling of the Majorana edge mode to trapped Majorana zero modes
in the bulk. Such tunneling breaks translational invariance and allows scattering between Majorana
and other edge modes in such a way that there is a parametric difference between the length scales
for equilibration of charge and heat transport between integer and Bose mode on the one hand, and
for thermal equilibration of the Majorana edge mode on the other hand. We discuss a parameter
regime in which this mechanism could explain the recent observation of quantized heat transport
