Atomic Trapping and Cooling Laser cooling and trapping is the ability to cool atoms down to unprecedented kinetic temperatures, and to confine and support isolated atoms in “atom traps”. This unique new level of control of atomic motion allows researchers to study the behavior of atoms and quantum mechanical properties. Atom Cooling and Trapping The ability to cool, manipulate, and trap atoms using laser light has allowed a new, rapidly expanding field to emerge. Recent publications noting the potential of reaching atomic kinetic-energy temperatures lower than absolute zero, otherwise known as negative temperatures, is one of the most impressive achievements to come out of this field.

2013-08-15 · In our last installment of the cold-atom toolbox series, we talked about why you need magnetic traps to get to really ultra-cold samples– because the light scattering involved in laser cooling limits you to a temperature that’s too high for making Bose-Einstein condensation (BEC).

Congratulations to Jason, Ruwan, and Randy! Rev. Sci. Instrum. 91, 011101 (2020). The primary mechanism by which laser cooling slows down atoms is by causing them to absorb and emit photons in random directions. As long as the velocity of the atom is greater than the recoil velocity of photon emission, the overall velocity is reduced.
