Impossibility to describe repulsion with contact interaction
Impossibility to describe repulsion with contact interaction
Morawetz, K.; Maennel, M.
Contact interactions always lead to attractive behaviour. Arguments are presented to show why a repulsive interacting system, e.g. Bose gases, cannot be described by contact interactions and corresponding treatments are possibly obscured by the appearance of bound states.
