Optical pumping of strontium atoms for laser cooling and imaging
Jens Samland, Shayne Bennetts, Chun-Chia Chen +3
We present a faster repumping scheme for strontium magneto-optical traps operating on the broad laser cooling tran…
A steady-state magneto-optical trap of fermionic strontium on a narrow-line transition
Rodrigo González Escudero, Chun-Chia Chen, Shayne Bennetts +2
A steady-state magneto-optical trap (MOT) of fermionic strontium atoms operating on the 7.5 kHz-wide transition is demonstrated. This MOT feat…
Continuous Bose-Einstein condensation
Chun-Chia Chen, Rodrigo González Escudero, Jiří Minář +3
Bose-Einstein condensates (BECs) are macroscopic coherent matter waves that have revolutionized quantum science and atomic physics. They are essential to quantum simulation and sen…
Continuous guided strontium beam with high phase-space density
Chun-Chia Chen, Shayne Bennetts, Rodrigo González Escudero +2
A continuous guided atomic beam of with a phase-space density exceeding in the moving frame and a flux of is…
The frequency of the ultranarrow transition in
Oleksiy Onishchenko, Sergey Pyatchenkov, Alexander Urech +4
We determine the frequency of the ultranarrow transition by spectroscopy of an ultracold gas. This transition is referenc…
Sisyphus Optical Lattice Decelerator
Chun-Chia Chen, Shayne Bennetts, Rodrigo González Escudero +2
We experimentally demonstrate a variation on a Sisyphus cooling technique that was proposed for cooling antihydrogen. In our implementation, atoms are selectively excited to an ele…
The RbSr ground state investigated via spectroscopy of hot & ultracold molecules
Alessio Ciamei, Jacek Szczepkowski, Alex Bayerle +9
We report on spectroscopic studies of hot and ultracold RbSr molecules, and combine the results in an analysis that allows us to fit a potential energy curve (PEC) for the X(1)$^2Σ…
A steady-state magneto-optical trap with 100 fold improved phase-space density
Shayne Bennetts, Chun-Chia Chen, Benjamin Pasquiou +1
We demonstrate a continuously loaded magneto-optical trap (MOT) with a steady-state phase-space density of . This is two orders of magnitu…
Efficient production of long-lived ultracold Sr molecules
Alessio Ciamei, Alex Bayerle, Chun-Chia Chen +2
We associate Sr atom pairs on sites of a Mott insulator optically and coherently into weakly-bound ground-state molecules, achieving an efficiency above 80\%. This efficiency is 2.…
