| Intrinsic and extrinsic origins of the polar Kerr effect in a chiral p-wave superconductor (2008) | |||||||||
Abstract | |||||||||
| Recently, the measurement of the polar Kerr effect (PKE) in the quasi two-dimensional superconductor Sr2RuO4, which is motivated to observe the chirality of px + i py-wave pairing, has been reported. The PKE has intrinsic and extrinsic (disorder-induced) origins. We show that the extrinsic contribution would be dominant in the PKE experiment..
