Title: 玻色-爱因斯坦凝聚体中里德堡 Dressing 量子液滴的表面激发

Abstract: 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. Show Chinese abstract

Abstract: 我们考虑了里德堡原子内的电子中双组分玻色-爱因斯坦凝聚体（BEC）的量子液滴，以使用博戈利乌伯理论研究集体激发的表面模式。我们计算了不同里德堡电子-原子相互作用强度下的表面激发谱。从能量谱中，我们计算了液滴的表面张力作为里德堡电子-原子相互作用强度的函数。我们的研究表明，电子-原子相互作用增强了表面能；因此，液滴在里德堡原子的电子内将更加稳定。
