    "abstract": "We show that a nonlinear Hamiltonian evolution can transform an SU(3)\ncoherent state into a superposition of distinct SU(3) coherent states, with a\nsuperposition of two SU(2) coherent states presented as a special case. A phase\nspace representation is depicted by projecting the multi-dimensional $Q$-symbol\nfor the state to a spherical subdomain of the coset space. We discuss\nrealizations of this nonlinear evolution in the contexts of nonlinear optics\nand Bose--Einstein condensates.",
