Laser cooling of antihydrogen atoms. [PDF]
Nature, 2021 AbstractThe photon—the quantum excitation of the electromagnetic field—is massless but carries momentum. A photon can therefore exert a force on an object upon collision1. Slowing the translational motion of atoms and ions by application of such a force2,3, known as laser cooling, was first demonstrated 40 years ago4,5. It revolutionized atomic physics

Laser cooling with intermediate state of spin–orbit coupling of LuF molecule [PDF]
Scientific Reports, 2023 This work presents a theoretical study of the laser cooling feasibility of the molecule LuF, in the fine structure level of approximation. An ab-initio complete active space self-consistent field (CASSCF)/MRCI with Davidson correction calculation has ...

Simulation of laser-Compton cooling of electron beams for future linear colliders [PDF]
Physical Review Special Topics. Accelerators and Beams, 2001 We study a method of laser-Compton cooling of electron beams for future linear colliders. Using a Monte Carlo code, we evaluate the effects of the laser-electron interaction for transverse cooling. The optics with and without chromatic correction for the

Laser cooling to quantum degeneracy [PDF]
Physical Review Letters, 2013 We report on Bose-Einstein condensation (BEC) in a gas of strontium atoms, using laser cooling as the only cooling mechanism. The condensate is formed within a sample that is continuously Doppler cooled to below 1\muK on a narrow-linewidth transition ...
