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 CuO 2 plane. Through the Chern-Simons term, holes behave like skyrmion excitations in a spin system and become a superconducting state with d x 2 - y 2 symmetry after the antiferromagnetic long-range order is destroyed.

Doping dependence of the Neel temperature in mott-hubbard antiferromagnets: effect of vortices
TLDR
The doping-dependent Neel temperature is calculated in good agreement with experiments for high- T(c) cuprates and the critical doping where long-range order vanishes at zero temperature is predicted to be x(c), independently of any energy scales of the system. Expand

It is shown that the spin-\textonehalf{} Heisenberg model is also the strong-coupling limit of an SU(2) lattice gauge theory with fermions, and the local SU( 2) gauge symmetry is manifest. Expand

TLDR
It is shown that several different order parameters can be used to characterize a type of P- and T-violating state for spin systems, that are called chiral-spin states, and speculated that superconducting states with unusual values of the flux quantum may exist. Expand
