论文摘要
传统分子中的振动动力学通常发生在picseconds或较短的时间表上。惊人的例外是Ultrange Rydberg分子，由于巨大的键长的长度高达几微米，因此动力学大大减慢。在这里，我们报告了最近观察到的rydberg-atom-ion分子的振动动力学的直接观察。通过应用几个MV/cm的弱外电场，我们能够控制光相关的超高范围Rydberg分子的方向，并通过淬灭电场来诱导振动动力学。高分辨率离子显微镜使我们能够检测到分子的方向及其在真实空间中的时间振动动力学。我们的研究为控制Rydberg分子中分子动力学的控制打开了大门。
Vibrational dynamics in conventional molecules usually takes place on a timescale of picoseconds or shorter. A striking exception are ultralong-range Rydberg molecules, for which dynamics is dramatically slowed down as a consequence of the huge bond length of up to several micrometers. Here, we report on the direct observation of vibrational dynamics of a recently observed Rydberg-atom-ion molecule. By applying a weak external electric field of a few mV/cm, we are able to control the orientation of the photoassociated ultralong-range Rydberg molecules and induce vibrational dynamics by quenching the electric field. A high resolution ion microscope allows us to detect the molecule's orientation and its temporal vibrational dynamics in real space. Our study opens the door to the control of molecular dynamics in Rydberg molecules.
