Attosecond Science : Looking into nature that has never been explored …

본문

" The endeavour to explore the microcosm in ever smaller dimensions is never ending. Structure and dynamics are most directly accessed in space and time, by means of microscopy and chronoscopy. Individual atoms can now be resolved and made perceivable in molecules and condensed matter by state-of-the-art microscopes when they are at rest. Also, their motion on the length scale of internuclear distances can be resolved and tracked with femtosecond laser techniques. However, the electronic structure and processes at a sub-atomic scale remained largely inaccessible in space and time until recently. �

Fundamental processes of chemistry, biology and materials science are triggered or mediated by the motion of electrons inside or between atoms. Electronic motion forms the basis for a wide range of modern technologies, including micro- and nano-electronics, photovoltaics, laser machining, bioinformatics, molecular biology, as well as medical diagnostics and theraphies. The atomic-scale motion of electrons typically unfolds within tens to thousands of attoseconds (1 attosecond [as] = 10-18 s). Recent breakthroughs in laser science are now opening the door to watching and controlling these hitherto inaccessible microscopic dynamics. They herald a new age of experimental physics: attosecond science provides � for the first time � direct access to any microscopic motion occurring outside the atomic core.�

In this talk, attosecond science and its recent progress will be briefly reviewed. The plan and research opportunities at CASTECH and Max Planck Center for Attosecond Science will be introduced."
