抄録

The chiral optical absorption by a single vortex in ap_x ± ip_y-wave superconductor is studied theoretically.The p_x±ip_y-wave state was recently suggested as the symmetryof the order parameter of Sr₂RuO₄ superconductor.Due to the violation of time reversal symmetry, there are two types of vortices whose winding orientation is the sameor opposite to the angular momentum of the Cooper pair. In a real material domains with p_x±ip_y-wave states are expected.However, optical absorption of circular polarized lightdepends only on the winding of the vortexand has a low energy absorption peak which results in dichroism.Dichroism occurs if superconductivity is realized on a single Fermisurface sheet. However, in the case of several Fermi surface sheets dichroism may disappear, if the both types of carriers are present, electron-like and hole-like. Therefore chiral optical absorption is a possible experimentto detect the orbital dependent superconductivitywhich was suggested as the superconducting state of Sr₂RuO₄.
