    "abstract": "We have identified a class of many body problems with analytic solution\nbeyond the mean-field approximation. This is the case where each body can be\nconsidered as an element of an assembly of interacting particles that are\ntranslationally frozen multi-level quantum systems and that do not change\nsignificantly their initial quantum states during the evolution. In contrast,\nthe entangled collective state of the assembly experiences an appreciable\nchange. We apply this approach to interacting three-level systems.",
