The Progress and Opportunities of the Quantum Coherent Controlling of Chemical Reactions

摘要: 1995年,人们曾预言"量子控制多体动力学将成为化学物理的主流"(引自第20届Solvay化学会议上Stuart A.Rice的主旨演说.Solvay会议是研讨未来科学的高级会议.这一届会议的主题是"光化学: 化学反应及其飞秒尺度上的控制"). 现在, 我们看到了这股潮流正源源而来,每年都不断地在Nature、 Science等杂志上刻下了里程碑.……Abstract: The progress in the quantum coherent controlling of chemical reactions is briefly reviewed. The controlling was firstly realized by modulating the phasa angle between one-photon and three-photon excitation of some molecules. The fluorescence intensities of atom in gaseous phase or molecules in liquid phase,as well as the dissociation branching of molecules were also controlled by self-optimizing the phase and the amplitude of an ultrafast laser pules. Some new possible propress of coherent control may appearin strong laser field,in condense phase or on catalysts.
