Phys. Rev. Lett. 95, 190403 (2005) [4 pages]Observation of Phase Defects in Quasi-Two-Dimensional Bose-Einstein CondensatesReceived 22 June 2005; published 1 November 2005 We have observed phase defects in quasi-2D Bose-Einstein condensates close to the condensation temperature. Either a single or several equally spaced condensates are produced by selectively evaporating the sites of a 1D optical lattice. When several clouds are released from the lattice and allowed to overlap, dislocation lines in the interference patterns reveal nontrivial phase defects. © 2005 The American Physical Society URL:
