Quantum Hall effects in layered disordered superconductors.

Layered singlet paired superconductors with disorder and broken time reversal symmetry are studied, demonstrating a phase diagram with charge-spin separation in transport. In terms of the average intergrain transmission and the interlayer tunneling we find quantum Hall phases with spin Hall coefficients of sigma(spin)(xy)=0,2 separated by a spin metal phase. We identify a spin metal-insulator l...

Quantum Hall effects and edge states in layered disordered superconductors

Layered singlet paired superconductors with disorder and broken time reversal symmetry are studied focusing on edge states and the corresponding quantum Hall effects. We find quantum Hall phases with spin Hall coefficients of σ xy = 0, 2 separated by a spin metal phase. We identify a spin metal-insulator localization exponent as well as a spin conductivity exponent of ≈ 0.96. In presence of a Z...
