One-dimensional multicomponent fermions with δ-function interaction in strong- and weak-coupling limits: κ-component Fermi gas

Guan, Xi-Wen; Ma, ZhongQi; Wilson, Brendan


The Fredholm equations for one-dimensional two-component fermions with repulsive and with attractive δ-function interactions are solved by an asymptotic expansion for strong repulsion, weak repulsion, weak attraction, and strong attraction. Consequently,
