Abstract

We show that a Chern-Simons term for a gauge field describing a fluctuation of spins is induced by integrating out hole fields in the presence of spin-orbit coupling which originates from a buckling of the CuO2_2 plane. Through the Chern-Simons term, holes behave like skyrmion excitations in a spin system and become a superconducting state with dx2y2d_{x^2-y^2} symmetry after the antiferromagnetic long-range order is destroyed.
