Title              :Direct probing attosecond dynamics of two-electron wave packet
Abstract        :
Real-time monitoring ultrafast electron dynamics in atomic and molecular systems can be carried out by a pump-probe set up in which the electronic wave packets are triggered by a pump pulse and subsequently probed by another pulse. Compared to bound states, a wave packet consisting of multiply-excited states is of more interest since the latters display much richer dynamics due to strong electron correlation. Recent study  [PRL 105, 053002 (2010)] shows that  the coherent superposition of doubly-excited states created by the XUV pulse ejects electrons in bursts rather than continuously. Moreover, XUV pump IR-probe simulation demonstrates that it is possible to exploit this dynamics to effectively control the branching ratios of the different ionization channels. In this talk, we will introduce those interesting observations. Relevant aspects in our ongoing study are also presented.
