Coupled-Channels Approach for Dissipative Quantum Dynamics in Near-Barrier Collisions

Diaz-Torres, Alexis; Dasgupta, Mahananda; Milburn, Gerard James; Tostevin, Jeffrey Allan; Hinde, David

Description

A novel quantum dynamical model based on the dissipative quantum dynamics of open quantum systems is presented. 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...[Show more]
