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 ...

A method for loading magneto-optical trap in an ultrahigh vacuum environment
AIP Advances, 2023 We have developed a method that enables loading a magneto-optical trap (MOT) in an ultrahigh vacuum environment. Nearly 1.0 × 108 atoms of 87Rb are trapped in the MOT at ∼2.0×10−10 Torr base pressure in the chamber.

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 ...

Magneto-optical trap of titanium atoms
Physical Review ResearchWe realize a magneto-optical trap (MOT) of titanium (Ti) atoms, performing laser cooling on the 498 nm transition between the long-lived 3d^{3}(^{4}F)4sa^{5}F_{5} metastable state and the 3d^{3}(^{4}F)4py^{5}G_{6}^{o} excited state.

Deep Laser Cooling of Thulium Atoms to Sub-µK Temperatures in Magneto-Optical Trap
Atoms, 2023 Deep laser cooling of atoms, ions, and molecules facilitates the study of fundamental physics as well as applied research. In this work, we report on the narrow-line laser cooling of thulium atoms at the wavelength of 506.2nm with the natural linewidth ...

Circular Magneto-Optical Trap for Neutral Atoms [PDF]
Journal of the Physical Society of Japan, 2008 We propose and experimentally demonstrate a novel scheme to magneto-optically trap neutral atoms in a ring shaped trap that can be used to transfer atoms into a circular magnetic trap with high density. This inturn enables to evaporatively cool atoms and study the behaviour of ultra cold gases in a periodic 2-dimensional potential. The circular magneto-

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
