Our research centers upon measuring and controlling dynamics in atomic and molecular systems using shaped ultrafast laser pulses. We are working to develop new time resolved spectroscopies to follow the quantum dynamics of electrons and nuclei in molecular systems. Our approach is to work on experiments of varying complexity, and to understand our experimental results through both simple intuitive models and detailed calculations.

The movie displays an electronic wave packet generated and probed with shaped ultrafast laser pulses. The movie shows the electron density in molecular thiophene as a function of the relative phase between two electronic eigenstates that are excited by a pump pulse and probed with a second pulse whose relative phase is controlled independent of delay.
