Disorder-enhanced topological protection and universal quantum criticality in a spin-3/2 topological superconductor
The study investigates Majorana surface states in spin-3/2 topological superconductors, generalizing 3He-B. While clean surfaces show instability towards a thermal quantum Hall effect upon interaction, quenched disorder stabilizes the system into a critical Conformal Field Theory (CFT). This disorder enhances topological protection and leads to quantized thermal transport at low temperatures, suggesting an analogy with the integer quantum Hall effect.
