One-dimensional magneto-optical compression of a cold CaF molecular beam [PDF]
New Journal of Physics, 2017 We demonstrate the one-dimensional, transverse magneto-optical compression of a cold beam of calcium monofluoride (CaF). By continually alternating the magnetic field direction and laser polarizations of the magneto-optical trap (RF MOT), a photon ...

Photonic integrated beam delivery for a rubidium 3D magneto-optical trap [PDF]
Nature Communications, 2023 Cold atoms are important for precision atomic applications including timekeeping and sensing. The 3D magneto-optical trap (3D-MOT), used to produce cold atoms, will benefit from photonic integration to improve reliability and reduce size, weight, and ...

Multiparameter optimisation of a magneto-optical trap using deep learning [PDF]
Nature Communications, 2018 Dynamics in cold atomic ensembles involve complex many-body interactions that are hard to treat analytically. Here, the authors use machine learning to optimise the cooling and trapping of neutral atoms, showing an improvement in the resulting resonant ...

Compact, ultra-high vacuum compatible, high power density conductive heaters
AIP Advances, 2023 We present a design and evaluation of a simple and easy-to-fabricate conductive heater intended for ultra-high vacuum experiments. We demonstrate a compact and power-dense heater that has minimal outgassing up to nearly 200 °C. We further detail a method

Vacuum pressure measurement of cold 7Li atoms in the magneto-optical and magnetic trap
AIP Advances, 2023 Cold atoms play a very important role in metrology. The ultra-high or extreme-high vacuum pressure can be accurately measured by investigating the collision of cold atoms and residual atoms in the environment. We report a vacuum pressure metrometer using

Dipolar Bose–Einstein condensation of 168Er and anisotropic expansion dynamics
Results in Physics, 2023 We report on the realization of Bose–Einstein condensation (BEC) of 168Er atoms in a crossed optical dipole trap. A magneto-optical trap is realized with just one laser driving the narrow-line transition which increases the phase space density and ...
