Abstract

The paper reports on the development of a locally optimized control theory of a time-dependent quantum system in nonstationary radiation fields. The theory is based on the control theory of a linear time-invariant (LTI) system. This theoretical method is then applied to a quantum mechanical system that obeys the time-dependent Schrodinger equation and the locally optimized external field is derived. The application of the theory to a ring-puckering isomerization of a molecule, such as trimethylenimine, on the ground electronic state, is presented. Both the control of isomerization were analyzed by the optimized field based on wave packet dynamics and the time dependence of the vibrational eigenstate distribution.
