摘要
利用平均场法计算了里德堡原子的偶极相互作用,分析了主量子数、拉比频率以及原子密度等对偶极阻塞效应的影响.随着主量子数以及原子密度的增大,原子间的相互作用增强,里德堡原子的偶极阻塞效应越明显;激光功率的增加,能提高里德堡原子的激发几率,但激发几率会趋于饱和,此时里德堡原子间的偶极阻塞效应最为显著.里德堡原子的偶极阻塞效应广泛应用于量子信息等领域.
The dipole interactions between Rydberg atoms are calculated by mean-field method, the dipole blockade effects are analyzed with different principal quantum numbers, Rabi frequencies and atomic densities. The larger the principal quantum number and atomic density are, the stronger the dipole interactions are and the more obvious the Rydberg dipole blockade effect is. The increasing of laser power can improve the population of Rydberg state. But the population will get saturated, when the dipole blockade effect is most significant. Rydberg dipole blockade effect is widely used in quantum information.
