Rydberg Interaction-Induced Distortion of the Autler–Townes Spectra in Cold Lithium Atoms
In this article, effects of the strong long-range interaction of Rydberg atoms on the Autler–Townes splitting spectrum are investigated. Preliminary results are obtained for various excitation times and Rydberg atom densities. The <inline-formula><math xmlns="http://www.w3.org/1998/Mat...

Interactions between Rydberg atoms excited by the probe beam lead to the broadening of the Autler–Townes spectra. At high concentrations of Rydberg atoms, a suppression of the excitation of the Autler–Townes peak at red detuning is observed. |
