Abstract

Recent breakthroughs in the ultrafast lasers development have allowed 
for the opening of new
horizons in the ultrafast experimental and theoretical AMO physics. 
Following these advances,
table-top light sources have provided novel ways to achieve a real-time 
manipulation of the
correlated electron/nuclear wavepacket dynamics by means of attosecond 
XUV and femtosecond
IR radiation [1-6]. However, more than fifteen years upon the birth of 
attosecond physics, and
after the Nobel Prize Award for femtochemistry, the concept of 
attosecond chemistry has not yet
been fully realized. In this talk, I will introduce the basic principles 
of the strong laser-field
ionization and generation of attosecond XUV/X-Ray radiation, and show 
how the attosecond VUV
and XUV light sources can be used to coherently manipulate molecular 
dynamics by means of
electron wave packet interferometry [7-9]. The use of attosecond VUV 
pulse-trains to coherently
excite and control the outcome of a simple chemical reaction in a 
deuterium molecule, in a nonBorn-Oppenheimer
regime, presents intriguing new possibilities for bridging the gap 
between the
attosecond physics and attochemistry [10]. Furthermore, I will discuss 
very recent results that
extend the use of the attosecond table-top techniques to the soft X-Ray 
regime in the water
window [11].

Short Biography: Predrag Ranitovic got his PhD from University of 
Stockholm. His thesis was based on the
experimental work performed at Kansas State University where he 
developed experiments for 3D
momentum imaging of small atoms and molecules by attosecond XUV 
radiation. He continued developing
methods for attosecond coherent control of electron and molecular 
dynamics in the Kapteyn-Murnane group
at University of Colorado and JILA at Boulder. At JILA, he also 
performed electron holography experiments
by utilizing strong mid-IR laser radiation. After UC-Boulder, he moved 
to Lawrence Berkeley National Lab
where he was applying time-resolved femtosecond IR and attosecond XUV 
methods to coherently control
electron dynamics in nano-materials. During his stay at LBNL he was a 
group leader at ELI-ALPS – the first
large-scale laser user facility currently built in EU.
Presently, Predrag is on sabbatical as a senior scientist at ETH – 
Zurich, and an LBNL affiliate.
