    <p>Recent breakthroughs in ultrafast lasers development have allowed for 
the opening of new horizons in the ultrafast experimental and theoretical AMO 
physics. Following these advances, table-top extreme ultraviolet (XUV) 
sources have provided novel ways to achieve real-time manipulation of 
electron dynamics through the use of attosecond XUV light coupled with strong 
laser fields in a time-resolved manner [1-6]. However, more than ten 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 show some recent advances in strong-field 
ionization done by mid-IR laser fields, and show how to use attosecond VUV 
and XUV light sources to coherently manipulate molecular dynamics by means of 
electron wave packet interferometry [7]. This novel approach of using 
attosecond vacuum ultraviolet pulse-trains to coherently excite and control 
the outcome of a simple chemical reaction in a deuterium molecule, in a 
non-Born Oppenheimer regime, presents intriguing new possibilities for 
bridging the gap in between the attosecond physics and attochemistry [8].</p>
