WebJan 21, 2024 · Cooling atoms is equivalent to slowing them down, which makes them a lot easier to study. At room temperature, atoms whiz through the air at nearly the speed of … WebApr 3, 2003 · Single cesium atoms are cooled and trapped inside a small optical cavity by way of a novel far-off-resonance dipole-force trap, with observed lifetimes of 2 – 3 s.Trapped atoms are observed continuously via transmission of a strongly coupled probe beam, with individual events lasting ≃ 1 s.The loss of successive atoms from the trap N ≥ 3 → 2 → 1 …
WebIn the field of optical trapping of atoms, it has been known that light-assisted collisions between atoms can lead to trap loss. In an inelastic collision, the kinetic energy gained by an atom can exceed the potential of the trap, causing the atom to escape from the trap. ... Phillips, W.D.
