    "abstract": "We present a family of many-body models which are exactly solvable\nanalytically. The models are an extended n-body interaction\nLipkin-Meshkov-Glick model which considers spin-flip terms which are associated\nwith the interaction of an external classical field which coherently\nmanipulates the state of the system in order to, for example, process quantum\ninformation. The models also describe a two-mode Bose-Einstein condensate with\na Josephson-type interaction which includes n-particle elastic and inelastic\ncollisions. One of the models corresponds to the canonical two-mode\nBose-Einstein Hamitonian plus a term which we argue must be considered in the\ndescription of the two-mode condensate. Intriguingly, this extra term allows\nfor an exact and analytical solution of the two-particle collision two-mode BEC\nproblem. Our results open up an arena to study many-body system properties\nanalytically.",
