Quantum state tomography of dissociating molecules

Esben Skovsen, Henrik Stapelfeldt, Soren Juhl, Klaus Molmer

摘要:

使用断层重建,我们确定了完整的核间量子态,表示的Wigner函数,解离I2分子的飞秒时间分辨的位置和动量分布的原子碎片的基础上。实验数据记录的定时电离的光碎片与一个强烈的20 fs的激光脉冲。我们的重建方法,依赖于Jaynes的最大熵原理,也将适用于时间分辨的位置或动量数据与其他实验技术。

英文摘要:

Using tomographic reconstruction we determine the complete internuclear quantum state, represented by the Wigner function, of a dissociating I2 molecule based on femtosecond time resolved position and momentum distributions of the atomic fragments. The experimental data are recorded by timed ionization of the photofragments with an intense 20 fs laser pulse. Our reconstruction method, which relies on Jaynes' maximum entropy principle, will also be applicable to time resolved position or momentum data obtained with other experimental techniques.
