Tidal potential measured with distant optical clocks
Lei Hou, Xiang Zhang, Qiang Zhu +33
Fibre-linked optical clocks sense tidal changes of the gravitational potential, but separating overlapping tidal components and quantifying their precision remain challenging. Usin…
Ytterbium lattice clock with systematic uncertainty of and instability at the level
Qiang Zhu, Jingran Shi, Yuechen Zhang +8
We report an optical lattice clock based on Yb atoms with a total systematic uncertainty of . An in-vacuum buildup cavity was employed to enhance the la…
A double species Na and Rb Bose-Einstein condensate with tunable miscibility via an interspecies Feshbach resonance
Fudong Wang, Xiaoke Li, Dezhi Xiong +1
We have realized a dual-species Bose-Einstein condensate (BEC) of Na and Rb atoms and observed their immiscibility. Because of the favorable background intra- and int…
Production of a rubidium Bose-Einstein condensate in a hybrid trap with light induced atom desorption
Dezhi Xiong, Fudong Wang, Xiaoke Li +2
We report on the production of a rubidium Bose-Einstein condensate in a simplified vacuum apparatus. Magneto-optical traps with large numbers and ultra-high vacuum for moderately l…
Observation of Feshbach resonances between ultracold Na and Rb atoms
Fudong Wang, Dezhi Xiong, Xiaoke Li +2
We have successfully prepared an optically trapped ultracold mixture of Na and Rb atoms and studied their interspecies Feshbach resonances. Using two different spin c…
Measurement of phase fluctuations of Bose-Einstein condensates in an optical lattice
Bing Wang, Qiang Zhu, Hailong Zhou +3
Even at zero temperature, there exist phase fluctuations associated with an array of Bose-Einstein condensates confined in a one-dimensional optical lattice. We demonstrate a metho…
Multi-normal-mode splitting of a cavity in the presence of atoms -- towards the superstrong coupling regime
Xudong Yu, Dezhi Xiong, Haixia Chen +3
Multi-normal-mode splitting peaks are experimentally observed in a system with Doppler-broadened two-level atoms inside a relatively long optical cavity. In this system, the atoms-…
