It allows the treatment of both deep-inelastic processes and quantum tunneling (fusion) within a fully quantum mechanical coupled-channels approach. Model calculations show the transition from pure state (coherent) to mixed state (decoherent and dissipative) dynamics during a near-barrier nuclear collision. Energy dissipation, due to irreversible decay of giant-dipole excitations of the interacting nuclei, results in hindrance of quantum tunneling.Keywords: Coupled channels; Decoherence; Deep -inelastic collisions; Dissipation; Fusion; Lindblad equation; Open quantum system; Quantum tunneling200910.1063/1.31088592016-02-24
