Outline

We aim at developing spectroscopic and optical methods to analyze and control quantum processes in atoms and molecules. Current studies are as follows:

• Photoionization study as an analysis of the simplest quantum process
• Atto-second quantum phase control in nuclear and electronic wave-packets
• Probing and controlling Femto-second decay dynamics of core-excited species
• Developing frequency- and time-domain spectroscopy of transient species
