Abstract
In a quasi-two-dimensional -wave superconductor there find six Cooper pairing states which are degenerate within the weak-coupling approach. We show that this degeneracy can be lifted by feedback effect favoring the so-called chiral -wave state. This effect is based on the anomalous coupling between charge and current in a system with broken time reversal symmetry and parity.
