Imprinting atoms
Nir Davidson and colleagues from the Weizmann Institute of Science and the Technion-Israel Institute of Technology demonstrate how the images “2”, “6” and “9” appear before (left column) and after (right column) they have been stored in an atomic gas. For the image “2”, they also show how images can be slowed in an atomic gas (centre column) simply by exploiting the dispersive nature of the medium. The blurring of the images, which is a result of atomic diffusion, can be reduced by employing a “phase-shift” technique. (Credit: Nir Davidson group)
