论文摘要
提供了从电位井到开放空间的两个rydberg穿着颗粒（玻色子或费米子）的动力学的全面分析。我们表明，当相互作用强度调谐到一定的临界值以下时，主要的衰减机制从顺序隧穿转换为配对隧道。可以通过调整相互作用势的有效范围来修改这些临界值。通过比较玻色子和费米子的动力学，我们表明两种情况之间存在显着差异。特别是，增加相互作用范围会以相反的方式修改隧道速率，用于费米和玻色子。此外，对于费米文化系统，需要更强大的吸引力相互作用来实现配对隧道。该结果提供了对隧道系统动态的洞察力，并且鉴于最新的隧道实现了少数身体系统和原子的rydberg敷料，它们为将来的实验提供了希望。
A comprehensive analysis of the dynamics of two Rydberg-dressed particles (bosons or fermions) tunneling from a potential well into open space is provided. We show that the dominant decay mechanism switches from sequential tunneling to pair tunneling when the interaction strength is tuned below a certain critical value. These critical values can be modified by tuning the effective range of the interaction potential. By comparing the dynamics for bosons and fermions, we show that there are significant differences between the two cases. In particular, increasing the interaction range modifies the tunneling rate in opposite ways for fermions and bosons. Furthermore, for the fermionic system much stronger attractive interactions are needed to achieve pair tunneling. The results provide insight into the dynamics of tunneling systems and, in light of recent realizations of tunneling few-body systems and Rydberg dressing of atoms, they offer promise for future experiments.
