Ultrafast electron delocalization induced by a fs laser pulse is a well-known process in which electrons are ejected from the ions within the laser pulse duration.(1) However, the speed of electron localization on an atom by an excitation is unknown. Here, we demonstrate by means of x-ray absorption spectroscopy that an electron localization process into 4f states of a Eu-based correlated...

83. New Light on the Frontier Matter in Extreme Conditions

Dr Arianna Gleason (SLAC/Stanford)

The study of matter under extreme conditions is a highly interdisciplinary subject with broad applications to materials science, plasma physics, geophysics and astrophysics. Understanding the processes which dictate physical properties in warm dense plasmas and condensed matter, requires studies at the relevant length-scales (e.g., interatomic spacing) and time-scales (e.g., phonon period)....
