51. Imaging the Phase of an Evolving Bose-Einstein Condensate Wave Function
Published: 9/1/2000
Authors: J E Simsarian, J Denschlag, M Edwards, Charles W Clark, Lu Deng, Edward W Hagley, Kristian Helmerson, S L. Rolston, William D Phillips
Abstract: We demonstrate a spatially resolved autocorrelation measurement with a Bose-Einstein condensate (BEC) and measure the evolution of the spatial profile of its quantum mechanical phase. After releasing the BEC from the magnetic trap, the phase develop ...

54. Coherence Properties of an Atom Laser
Published: 1/1/2000
Authors: M Trippenbach, Y B Band, M Edwards, M R Doery, Paul S Julienne, Edward W Hagley, Lu Deng, M M Kozuma, Kristian Helmerson, S L. Rolston, William D Phillips
Abstract: We study the coherence properties of an atom laser, which operates by extracting atoms from a gaseous Bose-Einstein condensate via a two-photon Raman process, by analyzing a recent experiment [(Hagley et al., submitted to Phys. Rev. Lett. (1999)]. W ...

56. Generating Solitons by Phase Engineering of a Bose-Einstein Condensate
Published: 1/1/2000
Authors: J Denschlag, J E Simsarian, D L Feder, Charles W Clark, L A Collins, J Cubizolles, Lu Deng, Edward W Hagley, Kristian Helmerson, W P Reinhardt, S L. Rolston, B I Schneider, William D Phillips
Abstract: We demonstrate quantum phase engineering using two novel techniques that allow us to write and read the spatial phase of a Bose-Einstein condensate (BEC). We design and produce a quantum state by optically imprinting phasepatterns onto a condensate ...

59. Temporal, Matter-Wave Dispersion Talbot Effect
Published: 12/1/1999
Authors: Lu Deng, Edward W Hagley, J Denschlag, J E Simsarian, M Edwards, Charles W Clark, Kristian Helmerson, S L. Rolston, William D Phillips
Abstract: We demonstrate an exact Talbot effect based on the dispersion relation of matter waves. A short-pulse, optical standing wave is used to write a phase grating on a sodium condensate and a second, identical diffraction pulse is applied after a variabl ...

60. Measurement of the Coherence of a Bose-Einstein Condensate
Published: 10/1/1999
Authors: Edward W Hagley, Lu Deng, M M Kozuma, M Trippenbach, Y B Band, M Edwards, M R Doery, Paul S Julienne, Kristian Helmerson, S L. Rolston, William D Phillips
Abstract: We study the coherence properties of a Bose-Einstein condensates using an interference technique. Two 100 ns optical standing wave pulses are applied to a condensate with a variable time delay between them. Each standing wave phase grating makes sm ...
