Research output: Contribution to journalArticlepeer-review


Layered singlet paired superconductors with disorder and broken time-reversal symmetry are studied. The phase diagram demonstrates quantization of spin Hall conductance. In terms of the average intergrain transmission and the interlayer tunnelling we find quantum Hall phases with spin Hall coefficients of σxyspin=0,2 separated by a spin metal phase. We identify a spin metal-insulator localization exponent as well as a spin conductivity exponent of ≈1.0. In presence of a Zeeman term an additional σxyspin=1 phase appears.
