Resonance scattering in the three-body systems of atom-diatom and relevance to condensed matter physics

Three-body resonance scattering of atom-diatomic molecule systems involving internal excitations is discussed by fully allowing the topological phase (Berry phase) contribution. Earlier a generalized formalism (Phys. Rev, A 1 996, 53, 2433) of the three-body resonance scattering was presented by intr oducing the gauge potential (Berry connection). Based on this study we prov ide additional information on topological importance in resonance scatterin g involving the atom-diatomic molecule systems. The massive gauge field (Be rry connection) contribution which arises from a broken symmetry is discuss ed. Its relevance to condensed matter physics will be briefly highlighted i n connection with our recent theory of superconductivity.
