Phys. Rev. Lett. 103, 033003 (2009) [4 pages]Electromagnetically Induced Transparency and Light Storage in an Atomic Mott InsulatorReceived 1 March 2009; published 17 July 2009 We experimentally demonstrate electromagnetically induced transparency and light storage with ultracold 87Rb atoms in a Mott insulating state in a three-dimensional optical lattice. We have observed light storage times of ≃240 ms, 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. © 2009 The American Physical Society URL:
