主　　题：Rydberg atom superradiance van der Waals interaction 

摘      要：We investigate Rydberg |65D_(5/2) → |66P_(3/2) superradiance in dense ultracold cesium atoms,where the ground atoms are excited to |65D_(5/2) Rydberg states via two-photon excitation in a standard magneto-optical *** superradiant spectrum of |65D_(5/2) → |66P_(3/2) is obtained using the state-selective field ionization *** observe its dynamic evolution process by varying the delay time of ionization field *** results show that the evolution process of |65D_(5/2) →|66P_(3/2) is much shorter than its radiation lifetime at room temperature,which verifies the superradiance *** dependence of the superradiance process on Rydberg atoms number N_(e) and principal quantum number n is *** results show that the superradiance becomes faster with increasing N_(e),while it is suppressed for stronger van der Waals(vdW) *** has potential applications in quantum technologies,and the Rydberg atom is an ideal medium for *** system is effective for studying the strong two-body interaction between Rydberg atoms.
