Qingli Jing

During her studies, Qingli Jing has studied the interaction of small molecules with intense femtosecond (10-15 s) and attosecond (10-18 s) light pulses by using the Monte Carlo wave packet approach. The strong external fields alters the distribution of the electron cloud around the nuclei in a molecule.
The alteration of the electron clouds would result in a weakening or strengthening of the chemical bonds between the constituent atoms in the molecule and thus ultrafast nuclear motion of the molecule can be induced. It is known that molecular vibrational motion occurs on the femtosecond timescale.
To resolve and retrieve such fast nuclear dynamics in a small molecule exposed to ultrashort laser pulses, Qingli has conducted a thorough analysis of the nuclear kinetic energy release spectra following breakup of the molecule.
The interaction between molecules and ultrashort laser pulses has attracted lots of research interests since coherent control of ultrafast nuclear dynamics in molecules can be realized by adjusting the laser parameters of the applied laser pulses.

The PhD degree was completed at the Department of Physics and Astronomy, Science and Technology, Aarhus University.
