Griffiths phase in the thermal quantum Hall effect

Two-dimensional disordered superconductors with broken spin-rotation and time-reversal invariance, e.g., with px+ipy pairing, can exhibit plateaus in the thermal Hall coefficient (the thermal quantum Hall effect). Our numerical simulations show that the Hall insulating regions of the phase diagram c...
