Surface chiral metal and warped time-reversal symmetry
We develop theory of dichroism and spin-dichroism for Sr2RuO4 to describe the observed peculiarities in ARPES. It is based on a tight-binding model for t2g electrons used earlier and contains a crucial ingredient: warped time-reversal symmetry. It assures perfectly antisymmetric spin-integrated dichroic signal while keeping spin-resolved signal completely non-symmetric.
