Journal ArticleDOI
Generating solitons by phase engineering of a bose-einstein condensate
Johannes Hecker Denschlag,Jesse E. Simsarian,David L. Feder,David L. Feder,Charles W. Clark,Lee A. Collins,J. Cubizolles,J. Cubizolles,Lu Deng,Edward W. Hagley,Kristian Helmerson,William P. Reinhardt,William P. Reinhardt,Steven L. Rolston,Barry I. Schneider,William D. Phillips +15 more
TL;DR: 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.
Journal ArticleDOI
Ultraslow optical solitons in a cold four-state medium.
TL;DR: It is demonstrated, both analytically and numerically, that both bright and dark ultraslow optical solitons can occur in such a highly resonant medium with remarkable propagation characteristics.
Journal ArticleDOI
A Well-Collimated Quasi-Continuous Atom Laser
Edward W. Hagley,Lu Deng,Lu Deng,Mikio Kozuma,J Wen,Kristian Helmerson,Steven L. Rolston,William D. Phillips +7 more
TL;DR: Extraction of sodium atoms from a trapped Bose-Einstein condensate (BEC) by a coherent, stimulated Raman process is demonstrated and the extracted atomic wave packets strongly overlap, forming a highly directional, quasi-continuous matter wave.
Journal ArticleDOI
Coherent Splitting of Bose-Einstein Condensed Atoms With Optically Induced Bragg Diffraction
Mikio Kozuma,Lu Deng,Edward W. Hagley,J Wen,R. Lutwak,Kristian Helmerson,Steven L. Rolston,William D. Phillips +7 more
TL;DR: In this paper, the authors observed Bragg diffraction of a Bose-Einstein condensate of sodium atoms by a moving, periodic, optical potential and observed the trajectory of the split atomic wave packets in the confining magnetic potential.
Journal ArticleDOI
Four-wave mixing with matter waves
Lu Deng,Lu Deng,Edward W. Hagley,J Wen,Marek Trippenbach,Marek Trippenbach,Yehuda B. Band,Yehuda B. Band,Paul S. Julienne,Jesse E. Simsarian,Kristian Helmerson,Steven L. Rolston,William D. Phillips +12 more
TL;DR: In this article, a coherent four-wave mixing in which three sodium matter waves of differing momenta mix to produce, by means of nonlinear atom-atom interactions, a fourth wave with new momentum is presented.
