Abstract
We present an analysis of the Hall conductivity sigma_xy(omega; T) in time reversal symmetry breaking states of exotic superconductors. We find that the dichroic signal is nonzero in systems with interband order parameters.This new intrinsic mechanism may explain the Kerr effect observed in strontium ruthenate and possibly other superconductors. We predict coherence factor effects in the temperature dependence of the imaginary part of the ac Hall conductivity Im sigma_xy(omega; T), which can be tested experimentally.
