    "abstract": "As examples of quantum-\"classical\" coupling systems, multi-component systems\nare studied by semiclassical evaluations of the Feynman kernels in the\ncoherent-state representation. From the observation of the phase space caustics\ndue to the presence of the internal degree of freedom (IDF), two phenomena are\nexplained in terms of the semiclassical theory: (1) The quantum oscillations of\nthe IDF induce quantum interference patterns in the Hushimi representation; (2)\nChaotic dynamics destroys the coherence of the quantum oscillations.",
