Abstract
We identify an intrinsic, dissipationless Hall effect in multiband chiral
superconductors in the absence of a magnetic field (i.e., an anomalous
Hall effect). This effect arises from interband tunneling of chiral Cooper
pairs. We discuss the implications of this effect for the putative chiral
p-wave superconductor, Strontium Ruthenate, and show that it can contribute
significantly to polar Kerr rotation experiments. Since the magnitude of the
effect depends on the structure of the order parameter across the bands, this
result may be used to distinguish between different models proposed for the
superconducting state of Strontium Ruthenate.
