A strontium quantum-gas microscope

S Buob, J Höschele, V Makhalov, A Rubio-Abadal… - PRX Quantum, 2024 - APS
The development of quantum-gas microscopes has brought novel ways of probing quantum
degenerate many-body systems at the single-atom level. Until now, most of these setups …

Optical pumping of strontium atoms for laser cooling and imaging

J Samland, S Bennetts, CC Chen, RG Escudero… - Physical Review …, 2024 - APS
We present a faster repumping scheme for strontium magneto-optical traps operating on the
broad 5 s 2 1 S 0− 5 s 5 p 1 P 1 laser cooling transition. Contrary to existing repumping …

Atom-number enhancement by shielding atoms from losses in strontium magneto-optical traps

J Höschele, S Buob, A Rubio-Abadal, V Makhalov… - Physical Review …, 2023 - APS
We present a scheme to enhance the atom number in magneto-optical traps of strontium
atoms operating on the 461-nm transition. This scheme consists of resonantly driving the 1 S …

Novel repumping on 3P0→ 3D1 for Sr magneto-optical trap and Landé g factor measurement of 3D1

S Zhang, P Ramchurn, M Menchetti… - Journal of Physics B …, 2020 - iopscience.iop.org
We realize an experimental facility for cooling and trapping strontium (Sr) atoms and
measure the Landé g factor of 3 D 1 of 88 Sr. Thanks to a novel repumping scheme with the …

Rydberg blockade in an ultracold strontium gas revealed by two-photon excitation dynamics

C Qiao, C Tan, J Siegl, F Hu, Z Niu, Y Jiang… - Physical Review A, 2021 - APS
We demonstrate the interaction-induced blockade effect in an ultracold Sr 88 gas via
studying the time dynamics of a two-photon excitation to the triplet Rydberg series 5 sns 3 S …

Charge dynamics of a molecular ion immersed in a Rydberg-dressed atomic lattice gas

R Mukherjee - Physical Review A, 2019 - APS
Charge dynamics in an ultracold setup involving a laser-dressed atom and an ion is studied
here. This transfer of charge is enabled through molecular Rydberg states that are accessed …

An ultrastable laser system at 689 nm for cooling and trapping of strontium

C Qiao, CZ Tan, FC Hu, L Couturier, I Nosske, P Chen… - Applied Physics B, 2019 - Springer
We present a 689-nm cavity-based laser system for cooling and trapping strontium atoms.
The laser is stabilized to a high-finesse cavity by the Pound–Drever–Hall technique …

Limitation of single-repumping schemes for laser cooling of Sr atoms

N Okamoto, T Aoki, Y Torii - arXiv preprint arXiv:2406.18942, 2024 - arxiv.org
We explore the efficacy of two single-repumping schemes, $5 s5p\,{}^ 3P_2-5p^ 2\,{}^ 3P_2
$($481\,\mathrm {nm} $) and $5 s5p\,{}^ 3P_2-5s5d\,{}^ 3D_2 $($497\,\mathrm {nm} $), for a …
