We demonstrate the state dependence of the ponderomotive energy shift of Rydberg atoms in an optical lattice using microwave spectroscopy. Unique to Rydberg atoms, this dependence results from a state-dependent aspect ratio between Rydberg-atom size and lattice period. A semiclassical simulation reproduces all features observed in the microwave spectra and indicates the presence of trapped Rydberg atoms.
我们利用微波光谱学证明了在光晶格中里德伯原子的动势能移动的态依存性。这种依存性是里德伯原子特有的，它源于里德伯原子大小和晶格周期之间的一个与态有关的纵横比。半经典模拟再现了微波谱中观察到的所有特征，并表明存在被捕获的里德伯原子。
