Table 1 Classification of pairing potentials.Classification of pairing potentials.. Summary of the classification of pairing potentials Δ_{q}≡Δ_{2,q} of the spin ↓ states c±K+q↓† to lowest order in (*q*_{+}, *q*_{−}), with *q*_{±} = *q*_{x} ± *iq*_{y}. The potentials are classified for a given combination of (*n*, *j*), where *n* describes an *n*-fold rotation axis and *j* is the spin angular momentum. The chiral superconductor has total angular momentum 2*j*, and the effective orbital angular momentum of Δ_{q} is given by *l*.
