标题： Electronically excited cold ion crystals

摘要： 激光激发离子晶体至高能级和长寿命的电子态是一个真正的多体过程，即使实际上只有一个离子被激发。 这是内部和外部动力学之间强耦合的直接表现，并在结构相变附近最为明显。 在这里，我们展示利用高度激发态为离子晶体的相干操控提供了一种新方法。 这使得研究依赖于电子和振动动力学之间强耦合的现象成为可能，并为在保罗阱中对分子过程进行量子模拟开辟了一条道路。 显示英文摘要

摘要： The laser excitation of an ion crystal to high lying and long-lived electronic states is a genuine many-body process even if in fact only a single ion is excited. This is a direct manifestation of the strong coupling between internal and external dynamics and becomes most apparent in the vicinity of a structural phase transition. Here we show that utilizing highly excited states offers a new approach to the coherent manipulation of ion crystals. This permits the study of phenomena which rely on a strong coupling between electronic and vibrational dynamics and opens up a route towards the quantum simulation of molecular processes in a Paul trap.
