    "abstract": "A general algebraic approach, incorporating both invariance groups and\ndynamic symmetry algebras, is developed to reveal hidden coherent structures\n(closed complexes and configurations) in quantum many-body physics models due\nto symmetries of their Hamiltonians $H$. Its general ideas are manifested on\nsome recent new examples: 1) G-invariant bi-photons and a related\nSU(2)-invariant treatment of unpolarized light; 2) quasi-spin clusters in\nnonlinear models of quantum optics; 3) construction of composite particles and\n(para)fields from G-invariant clusters due to internal symmetries.",
