Laser cooling and trapping of atomic strontium for ultracold atom physics, high-precision spectroscopy and quantum sensors
F. Sorrentino, G. Ferrari, N. Poli +2
This review describes the production of atomic strontium samples at ultra-low temperature and at high phase-space density, and their possible use for physical studies and applicati…
Cooling and trapping of ultra-cold strontium isotopic mixtures
N. Poli, R. E. Drullinger, G. Ferrari +3
We present the simultaneous cooling and trapping of an isotopic mixture in a magneto-optical trap and we describe the transfer of the mixture into a conservative, far-off resonant…
Atom interferometry gravity-gradiometer for the determination of the Newtonian gravitational constant G
A. Bertoldi, G. Lamporesi, L. Cacciapuoti +7
We developed a gravity-gradiometer based on atom interferometry for the determination of the Newtonian gravitational constant \textit{G}. The apparatus, combining a Rb fountain, Ra…
Long-lived Bloch oscillations with bosonic Sr atoms and application to gravity measurement at micrometer scale
G. Ferrari, N. Poli, F. Sorrentino +1
We report on the observation of Bloch oscillations on the unprecedented time scale of severalseconds. The experiment is carried out with ultra-cold bosonic strontium-88 loaded into…
Cooling of Sr to high phase-space density by laser and sympathetic cooling in isotopic mixtures
G. Ferrari, R. E. Drullinger, N. Poli +2
Based on an experimental study of two-body and three-body collisions in ultracold strontium samples, a novel optical-sympathetic cooling method in isotopic mixtures is demonstrated…
