n.
The reduction of kinetic energy of atoms or molecules by means of a tunable laser, which, when set at a certain frequency, will cause approaching atoms that absorb photons to lose momentum.

The experiment, led by Nick Vamivakas, an assistant professor of optics, demonstrates that it is possible to levitate diamonds as small as 100 nanometers (approximately one-thousandth the diameter of a human hair) in free space, by using a technique known as laser trapping. "Now that we have shown we can levitate nanodiamonds and measure photoluminescence from defects inside the diamonds, we can start considering systems that could have applications in the field of quantum information and computing," said Vamivakas.
