摘要:

利用微波光谱技术观察到了冷里德伯原子之间的共振电偶极-偶极相互作用。用脉冲激光将磁光阱中激光冷却的Rb原子激发到45 d里德堡态。微波脉冲将这些里德伯原子的一部分转移到46 p态。然后,第二个微波脉冲将45 d态的原子驱动到46 d态,并被用作原子间相互作用的探针。发现这种双光子探测跃迁的光谱宽度依赖于46 p原子的存在,并且是由于45 d和46 p里德伯原子之间的共振电偶极-偶极相互作用。

英文摘要:

Resonant electric dipole-dipole interactions between cold Rydberg atoms were observed using microwave spectroscopy. Laser-cooled Rb atoms in a magneto-optical trap were optically excited to 45d Rydberg states using a pulsed laser. A microwave pulse transferred a fraction of these Rydberg atoms to the 46p state. A second microwave pulse then drove atoms in the 45d state to the 46d state, and was used as a probe of interatomic interactions. The spectral width of this two-photon probe transition was found to depend on the presence of the 46p atoms, and is due to the resonant electric dipole-dipole interaction between 45d and 46p Rydberg atoms.
