Threshold singularities in a Fermi gas with attractive potential in one dimension
We consider the one-dimensional gas of fermions with spin S interacting via an attractive δ-function potential using the Bethe Ansatz solution. In zero magnetic field the atoms form bound states of N=2S+1 fermions, i.e. generalized Cooper states with each atom having a different spin component. For...
