Abstract: In this project, we aim to realize the real-time observation of dynamical evolution of quantum states in atoms and molecules with ultrafast laser pulses and provide a comprehensive understanding of the complex interactions of atoms and molecules with intense laser fields. For this purpose, we will develop several key experimental techniques, including few-cycle laser pulse, many-particle coincident measurement, femtosecond pump-probe and atto-clock techniques. The above techniques will then be employed in the study of, e.g., the control of the ionizing electronic wavepackets driven by intense laser field, the field-free alignment of molecules, the real-time observation of the dynamical evolution of molecular quantum states in the molecular frame, the electron correlation effects on the dynamics of atoms and molecules. Combined with the experimental efforts, efficient theoretical approaches will be developed to facilitate a comprehensive understanding of the complex many-body dynamics in atoms and molecules subject to intense laser fields.
