Welcome to Technion’s Ultrafast Quantum Dynamics research group

In our new lab, we are studying coherent quantum dynamics on the atomic length and time scale. Coherence is at the heart of ultrafast electronic processes in atomic, molecular and solid systems. A brief perturbation by a light field causes a coherent response, transferring the coherence of the field to the dynamics of the electrons. The time scale associated with coherent electron dynamics in those systems is in the attosecond domain (1 as = 10^-18 s) . However, decoherence destroys the coherent evolution on time scales ranging from femtoseconds to nanoseconds. Fast decoherence, the intrinsic time scales and picometer to nanometer length scales make the direct observation of coherent dynamics challenging. Therefore we require extremely high spatial and temporal resolving power for the observation of those phenomena. In our new lab, we are developing new approaches to achieve exactly that – simultaneous spatial and temporal imaging of electronic wave functions.
