Eventually they will synchronize with opposite polarities and will reduce the noise in a very small area for a short period of time while increasing the noise everywhere else. The Quanta Newsletter. In three of the groups, in two independent studies , reported that they could cool down silica nanoparticles about to nanometers across, containing around a hundred million atoms, almost into their lowest-energy ground quantum state while holding them in an optical trap produced by laser beams. The method didn't cool other types of vibrations such as side-to-side motion of the disc-shaped crystal. But that limit, Schwab and his colleagues discovered, is not insurmountable.
