| Time resolved spectroscopy is a powerful tool to observe atomic and molecular processes in real time. Additionally, with novel pulse shaping devices, not only the observation, but also the active control of these processes through shaped laser light has become possible. Theoretical simulations of these processes in complex quantum systems, like large molecules or molecules subject to environments, is a great challenge since they require in principle a quantum dynamical approach of high dimensionality, together with control strategies to design external fields. One of these strategies is local control, where the instantaneous dynamics of a quantum system is used to design external fields in order to increase a predefined objective. In this presentation, the basic principle of local control theory is briefly reviewed and illustrated for simple systems, like electronic population transfer or vibrational cooling in diatomic molecules. |
