  • Title: Nonadiabatic chemical dynamics in an intense laser field: electronic wave packet coupled with classical nuclear motions.
    Author: Yagi K, Takatsuka K.
    Journal: J Chem Phys; 2005 Dec 08; 123(22):224103. PubMed ID: 16375466.
    Abstract:
    Dynamics of molecules in an intense laser field is studied in terms of the quantum electronic wave packet coupled with classical nuclear motions. The equations of motion are derived taking a proper account of molecular interactions with the vector potential of a classical electromagnetic field, along with the nonadiabatic interaction due to the breakdown of the Born-Oppenheimer approximation. With the aid of electronic structure calculations, the present method enables us to track, in an ab initio manner, the dynamics of polyatomic molecules in an intense field. Preliminary calculations are carried out for the vibrational state of LiF and a collision of Li+F under an intense laser pulse, which are limited to the domain of no ionization.
