This award supports two projects that focus on field-induced collective motion and quantum control in multi-electron and multi-atom systems. The experiments employ intense femtosecond pulses to excite and control isolated systems, and imagining instrumentation to monitor quantitatively energy and angular correlation between simultaneously ejected components. The subject of the first project is three-atom systems undergoing field-induced Coulomb explosion. The fact that the vibrational motion of linear and nonlinear triatomic molecules leads to different explosion dynamics will be exploited to control the branching ratio between explosion channels. In the second project two-atom systems will be studied. In particular, the coupling between the nuclear and electronic motion in the presence of strong laser fields will be investigated in the molecule HD.

该奖项支持两个项目，重点是场致集体运动和量子控制在多电子和多原子系统。 实验采用强烈的飞秒脉冲来激发和控制孤立的系统，并使用成像仪器来定量监测同时喷射的成分之间的能量和角度相关性。 第一个项目的主题是三原子系统经历场致库仑爆炸。 线性和非线性三原子分子的振动运动导致不同的爆炸动力学的事实将被利用来控制爆炸通道之间的分支比。 在第二个项目中，将研究双原子系统。 特别是，在强激光场的存在下，核和电子运动之间的耦合将在分子HD中进行研究。
