"Ultra-Intense Field Physics:Atomic Response"


Enam Chowdhury , University of Delaware
[Host: Bob Jones]
ABSTRACT:
There is a paradigm shift from high fields (below ~1016 W/cm2) to ultra-high fields, in terms of basic atomic response to the light field. Electron motion becomes relativistic, dipole approximation breaks down, magnetic fields of the light play an important role. What happens to an atom/ion in such an intense field? How are electron correlation effects (e.g. 2 electron wave-packet dynamics) modified? I will try to shed light on some of these topics. Also, I will discuss some novel techniques that we have developed to facilitate the achievements of such fields in table top experiments.
