论文摘要
我们建立了使用H $ _2 $分子作为示例的激光诱导的定向键断裂的相位敏感性的广义图。我们表明，众所周知的质子弹性各向异性用很少的循环脉冲测量，是作为固有各向异性的振幅调节，该固有各向异性在电离时间对激光相敏感并由分子的电子结构确定。此外，我们的工作还揭示了强烈的电子 - 蛋白质相关性，该相关性可能开辟了一种新的方法，可以在大分子中也可以实验地访问激光循环分子内电子动力学。
We establish a generalized picture of the phase-sensitivity of laser-induced directional bond-breaking using the H$_2$ molecule as the example. We show that the well-known proton ejection anisotropy measured with few-cycle pulses arises as an amplitude-modulation of an intrinsic anisotropy that is sensitive to the laser phase at the ionization time and determined by the molecule's electronic structure. Our work furthermore reveals a strong electron-proton correlation that may open up a new approach to experimentally accessing the laser-sub-cycle intramolecular electron dynamics also in large molecules.
