Composite operators for a BCS superconductor
Bonca J., Balatsky A. V.
A new form of the composite operator which generalizes the Cooper pairs for a BCS superconductor is introduced. This approach is similar to the derivation of the composite operator of the odd-frequency superconductors. Examples of the dxi_p., dxy, and />-wave composite operators for a 2D t-J model are given.
