Critical phenomena in gravitational collapse opened a new mathematical vista into the theory of general relativity and may ultimately entail fundamental physical implication in observations. However, ...
Collapses and revivals of stored orbital angular momentum of light in a cold atomic ensemble
Collapses orbital angular momentum light atomic ensemble
2010/4/8
We report on the storage of orbital angular momentum of light in a cold ensemble of cesium atoms. We employ Bragg diffraction to retrieve the stored optical information impressed into the atomic coher...
