Visible Efimov effect in the spectroscopy of Bose polarons

Associate Professor Xiaoling Cui
Institute of Physics, Chinese Academy of Sciences, Beijing, China


Bose polaron is generally believed as a promising many-body system to host the novel Efimov correlations. Nevertheless, no signature of Efimov physics has been reported in the existing Bose polaron experiments up to date. In this talk, I will show that the Efimov physics can be directly observed in the spectroscopy measurement of Bose polarons with large mass imbalance. Taking the 6Li(impurity)- 133Cs(bosons) system as an example, our calculation shows two visible Efimov branches in the spectral response of 6Li atoms, as well as the spectral broadening due to their hybridizations with the attractive polaron branch. These results suggest that the highly mass-imbalanced atomic mixtures can serve as an ideal platform for the observation of intriguing few-body correlations in a many-body environment.
