@article { , title = {Dephasing effect of Rydberg states on trap loss spectroscopy of cold atoms}, abstract = {In this paper, we investigate the asymmetry of trap loss spectra of ultracold atoms during the excitation of Rydberg states. It is shown that the profile of a trap loss spectrum is affected by the density of Rydberg atoms as well as the dephasing rate of Rydberg states. The splitting of a trap loss spectrum is shown at the higher dephasing rates of Rydberg states. A three-level model, where the dephasing rates can be ascribed mainly to a random collision of Rydberg atoms, reasonably explains the experimental results.}, doi = {10.1364/JOSAB.459064}, eissn = {1520-8540}, issn = {0740-3224}, issue = {8}, journal = {Journal of the Optical Society of America B}, pages = {2032-2036}, publicationstatus = {Published}, publisher = {Optica Publishing Group}, url = {https://nottingham-repository.worktribe.com/output/8857395}, volume = {39}, keyword = {Atomic and Molecular Physics, and Optics, Statistical and Nonlinear Physics}, year = {2022}, author = {Cao, Yifei and Yang, Wenguang and Zhang, Hao and Jing, Mingyong and Li, Weibin and Zhang, Linjie and Xiao, Liantuan and Jia, Suotang} }
