Spatially-selective in situ magnetometry of ultracold atomic clouds
Ottó Elíasson, Robert Heck, Jens S. Laustsen +5
We demonstrate novel implementations of high-precision optical magnetometers which allow for spatially-selective and spatially-resolved in situ measurements using cold atomic cloud…
Remote optimization of an ultra-cold atoms experiment by experts and citizen scientists
Robert Heck, Oana Vuculescu, Jens Jakob Sørensen +17
We introduce a novel remote interface to control and optimize the experimental production of Bose-Einstein condensates (BECs) and find improved solutions using two distinct impleme…
Measurement-enhanced determination of BEC phase transitions
Mark G. Bason, Robert Heck, Mario Napolitano +6
We demonstrate how dispersive atom number measurements during evaporative cooling can be used for enhanced determination of the parameter dependence of the transition to a Bose-Ein…
Generation of macroscopic singlet states in a cold atomic ensemble
N. Behbood, F. Martin Ciurana, G. Colangelo +4
We report the generation of a macroscopic singlet state in a cold atomic sample via quantum non-demolition (QND) measurement induced spin squeezing. We observe 3 dB of spin squeezi…
Ultrasensitive Atomic Spin Measurements with a Nonlinear Interferometer
R. J. Sewell, M. Napolitano, N. Behbood +3
We study nonlinear interferometry applied to a measurement of atomic spin and demonstrate a sensitivity that cannot be achieved by any linear-optical measurement with the same expe…
Feedback-cooling of an atomic spin ensemble
N. Behbood, M. Napolitano, G. Colangelo +4
We describe a measurement-and-feedback technique to deterministically prepare low-entropy states of atomic spin ensembles. Using quantum non-demolition measurement and incoherent o…
