Quantum Dynamics (FBB3130)
Quantum dynamics is the background of molecular and optical physics, which has
impact in different fields, from molecular dynamics and light propagation to different
applications like quantum computing, molecular electronics and material sciences. The QD is the front
page of modern physics and chemistry due to ultrashort laser infra-red and optical sciences pulses
(from femtosecond to attosecond time domains). Femtosecond x-ray pulses are already available in FLASH
(Hamburg) and Stanford Linear Accelerator Center. This new source of ultra-short x-ray pulses opens
unique opportunity to map molecular dynamics with the Ångström resolution which of crucial importance
in material sciences and biology. "Quantum dynamics" gives students important concept of the dynamics of
different physical chemical processes.
The course is intended for anyone who wishes to learn the current state of ultrafast phenomena in chemistry and physics.
