Carrier pairing in spin-liquid state of doped 2D antiferromagnet
Kogan Ya. I. , Khveshchenko D. V.
An effective infrared theory which describes the dynamics of charge carriers ir planar Cu02 antiferromagnet is discussed. This theory reduces to a gauge thee with a topological mass term. The condensation mechanism, the competition between the s~wave and/?-wave pairing, and the effective Ginzburg-Landau Lagrangian are discussed.
