摘要

我们考虑了雷德贝格原子电子内部的玻色-爱因斯坦凝聚态（BEC）两个分量的量子液滴，利用波哥留布夫激发理论研究了集体激发的表面模式。我们计算了不同雷德贝格电子原子相互作用强度下的表面激发能谱。根据能谱，我们计算了液滴的表面张力与 Rydberg 电子原子相互作用强度的函数关系。我们的研究表明，电子-原子相互作用增强了表面能；因此，液滴在雷德贝格原子的电子内会更加稳定。

Surface excitation of Rydberg dressed quantum droplet of Bose–Einstein Condensates

We have considered a quantum droplet of two components of Bose–Einstein condensate (BEC) inside the electron of a Rydberg atom to study the surface mode of collective excitation using the Bogoliubov theory of excitation. We have calculated the surface excitation spectrum for various Rydberg electron-atom interaction strengths. From the energy spectrum, we calculated the surface tension of the droplet as a function of Rydberg electron-atom interaction strength. Our study shows that the electron-atom interaction enhances the surface energy; hence, the droplet will be more stable inside the electron of a Rydberg atom.
