标题： Time-domain interferences as the source of electron-ion entanglement in Rabi-dressed photoemission

摘要： 我们研究光电子与其母离子之间的双粒子纠缠，当后者经历拉比振荡时，这是基于[Nandi等人]最近的实验[Science Advances 10, eado0668 (2024)]。通过在模型原子上的数值模拟，我们表明这种纠缠来自于不同时间发生的电离事件，由于拉比耦合，光电子离开离子时处于不同的内部状态叠加。我们的解释提出了从光电谱中获取光离子态纯度的可能性。此外，我们展示了从可观测谱中对“穿衣”离子态动力学的断层重建。 显示英文摘要

摘要： We investigate bipartite entanglement between a photoelectron and its parent ion when the latter undergoes Rabi oscillations, following the recent experiment of [Nandi et al. Science Advances 10, eado0668 (2024)]. Using numerical simulations on a model atom, we show that this entanglement results from ionization events occurring at different times, with the photoelectron leaving the ion in distinct superpositions of internal states due to the Rabi coupling. Our interpretation brings forward the possibility to access the purity of the photoion state from photoelectron spectra. Furthermore, we demonstrate a tomographic reconstruction of the dressed ionic state dynamics from the observable spectra.
