SUPERCONDUCTIVITY OF THE DOPED MOTT INSULATOR IN THE CSL PHASE

Abstract

The effective infrared theory of the planar CuO 2 antiferromagnetic (AFM) is investigated. In the Chiral Spin Liquid (CSL) phase this theory is the 2 + 1 gauge theory with topological mass (Chern-Simons) term and we obtain the attraction between charged fermions (holes). The last are isodublets as a consequence of the two sublattices existence. We get the gap equations for different waves and there is gap degeneracy between S and P waves. The ground state is P and T odd in the case of the P-wave pairing and there is the new term in the Ginzburg-Landau phenomenological Lagrangian, describing the layer's magnetization.
