Caltech Team Uses Laser Light to Cool Object to Quantum Ground State

Caption: A scanning electron microscope image (a) of the nanoscale silicon mechanical resonator used in the laser cooling experiment. The outer "cross" patterning forms the shield while the central beam region, the SEM image of which is shown in (b), forms an optical cavity where laser light is used to cool the mechanical motion of the beam. Numerical simulations of the localized optical field and mechanical breathing motion of the nanobeam are shown in panels (c) and (d), respectively.
