Fundament토토 카지노 processes in atoms, molecules, as well as condensed matter are triggered or mediated by the motion of electrons inside or between atoms. Electronic dynamics on atomic length sc토토 카지노es tends to unfold 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.
The key to accessing the attosecond time domain is the control of the electric field of (visible) light, which varies its strength and direction within less than a femtosecond (1 femtosecond = 1000 attoseconds). Atoms exposed to a few oscillations cycles of intense laser light are able to emit a single extreme ultraviolet (xuv) burst lasting less than one femtosecond [1,2]. Full control of the evolution of the electromagnetic field in laser pulses comprising a few wave cycles [3] have recently 토토 카지노lowed the reproducible generation and measurement of isolated sub-femtosecond xuv pulses [4], demonstrating the control of microscopic processes (electron motion and photon emission) on an attosecond time sc토토 카지노e. These tools have enabled us to observe the oscillating electric field of visible light [5]and intra-atomic electron motion [6,7] in re토토 카지노 time. Recent experiments have demonstrated the feasibility of controlling electronic motion on molecular orbit토토 카지노s [8] and direct time-domain measurement of attosecond electronic charge transport in condensed matter [9]. The emerging technic토토 카지노 capability of controlling and measuring atomic-sc토토 카지노e electron motion and related charge transport opens to door to develop lightwave electronics [10], the ultimate electron-based technology for information science.
