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.

Unified picture of Néel order destruction, d-wave superconductivity and the pseudogap phase for high Tc cuprates
Evolution from Neel order to dx2−y2-wave superconductivity in the high Tc cuprates is described in terms of the skyrmion-like spin texture induced by the doped hole. The pseudogap phase, which isExpand

Doping dependence of the Neel temperature in mott-hubbard antiferromagnets: effect of vortices
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
Spin-orbit coupling and spirals in doped La2CuO4.
Spin-orbit coupling in doped La 2 CuO 4 can result in (I) a novel electron-phonon coupling involving soft oxygen «tilting» phonons, and (2) stabilization of a commensurate antiferromagnetic stateExpand

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
