Generalized local interactions in 1D: solutions of quantum many-body systems describing distinguishable particles

As is well known, there exists a four-parameter family of local interactions in 1D. We interpret these parameters as coupling constants of delta-type interactions which include different kinds of momentum-dependent terms, and determine all cases leading to many-body systems of distinguishable partic...
