Dicke superradiance in ordered arrays of multilevel atoms

SJ Masson, JP Covey, S Will, A Asenjo-Garcia - PRX Quantum, 2024 - APS
In inverted atomic ensembles, photon-mediated interactions give rise to Dicke
superradiance, a form of many-body decay that results in a rapid release of energy as a …

Degenerate Fermi Gas of

BJ DeSalvo, M Yan, PG Mickelson… - Physical Review Letters, 2010 - APS
We report quantum degeneracy in a gas of ultracold fermionic Sr 87 atoms. By evaporatively
cooling a mixture of spin states in an optical dipole trap for 10.5 s, we obtain samples well …

Bose-Einstein Condensation of

YNM De Escobar, PG Mickelson, M Yan, BJ DeSalvo… - Physical review …, 2009 - APS
We report Bose-Einstein condensation of Sr 84 in an optical dipole trap. Efficient laser
cooling on the narrow intercombination line and an ideal s-wave scattering length allow the …

[CARTE][B] Degenerate quantum gases of strontium

S Stellmer, F Schreck, TC Killian - 2013 - World Scientific
All of the early experiments reaching Bose–Einstein condensation (BEC) 1 and the Fermi-
degenerate regime2 in ultracold gases were performed with alkali atoms. In recent years …

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 …

Bose-Einstein Condensation of Sr Through Sympathetic Cooling with Sr

PG Mickelson, YN de Escobar, M Yan… - ar** of strontium atoms for laser cooling and imaging
J Samland, S Bennetts, CC Chen, RG Escudero… - Physical Review …, 2024 - APS
We present a faster repum** 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 repum** …

Novel repum** 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 trap** strontium (Sr) atoms and
measure the Landé g factor of 3 D 1 of 88 Sr. Thanks to a novel repum** scheme with the …
