Abstract
We experimentally demonstrate electromagnetically induced transparency and light storage with ultracold atoms in a Mott insulating state in a three-dimensional optical lattice. We have observed light storage times of , to our knowledge the longest ever achieved in ultracold atomic samples. Using the differential light shift caused by a spatially inhomogeneous far detuned light field we imprint a “phase gradient” across the atomic sample, resulting in controlled angular redirection of the retrieved light pulse.
