The introduction of lasers in atomic physics experiments was the precursor to the laser cooling proposals in the mid 1970s. Laser cooling was proposed separately in 1975 by two different research groups: Hänsch and Schawlow, [9] and Wineland and Dehmelt. [10]
Ultracold atomic physics experiments on atomic species with poorly-resolved hyperfine structure, like isotopes of lithium [1] and potassium, [2] often utilize gray molasses instead of Sisyphus cooling as a secondary cooling stage after the ubiquitous magneto-optical trap (MOT) to achieve temperatures below the Doppler limit. Unlike a MOT, which ...
Optical molasses schematic. Optical molasses (OM) is a laser cooling technique that can cool neutral atoms to as low as a few microkelvins, depending on the atomic species. An optical molasses consists of 3 pairs of counter-propagating orthogonally polarized laser beams intersecting in the region where the atoms are present.

The idea of the atomic fountain was first proposed in the 1950s by Jerrold Zacharias. [6] [7] Zacharias attempted to implement an atomic fountain using a thermal beam of atoms, under the assumption that the atoms at the low-velocity end of the Maxwell–Boltzmann distribution would be of sufficiently low energy to execute a reasonably sized parabolic trajectory.

Atomic Blonde superfan Ariana DeBose had a blast channeling her inner Charlize Theron for her new action rom-com Love Hurts — even if it meant a daily dose of injuries. From veteran stunt ...
