| Outline of Final Research Achievements |
The purpose of this project is to develop a new quantum reaction dynamics theory, where all the atomic motions in the chemical system are described with quantum mechanics, in order to understand the role of nuclear quantum effects in complicated chemical reactions. We have developed a new hybrid simulation scheme in which the time-dependent quantum wave packet dynamics method is employed for the solute motion while the ring-polymer molecular dynamics (RPMD) method is used for the solvent motion. We have applied this new method to the photoexcitation dynamics process of the Ag-doped helium cluster system. Qualitative agreement between theory and experiment has been obtained.
