Description:
Quantum phase engineering is demonstrated with two techniques that allow the spatial phase distribution of a Bose-Einstein condensate (BEC) to be written and read out. A quantum state was designed and produced by optically imprinting a phase pattern onto a BEC of sodium atoms, and matter-wave interferometry with spatially resolved imaging was used to analyze the resultant phase distribution. An appropriate phase imprint created solitons, the first experimental realization of this nonlinear phenomenon in a BEC. The subsequent evolution of these excitations was investigated both experimentally and theoretically.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Denschlag -- Simsarian -- Feder -- Clark -- Collins -- Cubizolles -- Deng -- Hagley -- Helmerson -- Reinhardt -- Rolston -- Schneider -- Phillips -- New York, N.Y. -- Science. 2000 Jan 7;287(5450):97-101.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute of Standards and Technology (NIST), Gaithersburg, MD 20899, USA.
