论文摘要
众所周知,如果原子相互吸引,它们可以形成分子。在这里,我们表明可以创建分子,而原子的结合状态不是吸引人相互作用的结果,而是具有拓扑起源的结果。也就是说,原子的结合状态对应于拓扑模型的拓扑保护边缘状态。如果超冷原子之间的相互作用强度在时间上适当调节,则可以实现这种拓扑分子。类似的机制允许人们实现电子在经典轨道上拓扑保护的定位,如果rydberg原子受到正确调制的微波场的扰动。
It is common knowledge that atoms can form molecules if they attract each other. Here, we show that it is possible to create molecules where bound states of the atoms are not the result of attractive interactions but have the topological origin. That is, the bound states of the atoms correspond to the topologically protected edge states of a topological model. Such topological molecules can be realized if the interaction strength between ultra-cold atoms is properly modulated in time. A similar mechanism allows one to realize topologically protected localization of an electron on a classical orbit if a Rydberg atom is perturbed by a properly modulated microwave field.
