Journal ArticleDOI
Nonlinear atom interferometer surpasses classical precision limit
TL;DR: It is shown experimentally that the classical precision limit can be surpassed using nonlinear atom interferometry with a Bose–Einstein condensate and the results provide information on the many-particle quantum state, and imply the entanglement of 170 atoms.
Journal ArticleDOI
Squeezing and entanglement in a Bose-Einstein condensate
TL;DR: In this article, the authors demonstrate spin squeezed states suitable for atomic interferometry by splitting a Bose-Einstein condensate into a few parts using an optical lattice potential.
Journal ArticleDOI
Experimental Observation of Oscillating and Interacting Matter Wave Dark Solitons
A. Weller,Jens Philipp Ronzheimer,Christian Gross,Jérôme Estève,Markus K. Oberthaler,Dimitri J. Frantzeskakis,Georgios Theocharis,Panayotis G. Kevrekidis +7 more
TL;DR: An effective particle picture is developed and confirms that the deviation of the observed oscillation frequencies from the asymptotic prediction nu(z)/sqrt 2, where nu( z) is the longitudinal trapping frequency, results from the dimensionality of the system and the soliton interactions.
Journal ArticleDOI
Observations of Density Fluctuations in an Elongated Bose Gas: Ideal Gas and Quasicondensate Regimes
Jérôme Estève,Jérôme Estève,Jean-Baptiste Trebbia,Thorsten Schumm,Alain Aspect,Christoph I Westbrook,Isabelle Bouchoule +6 more
TL;DR: In situ measurements of density fluctuations in a quasi-one-dimensional 87Rb Bose gas at thermal equilibrium in an elongated harmonic trap observe an excess of fluctuations compared to the shot-noise level expected for uncorrelated atoms.
Journal ArticleDOI
Entangled States of More Than 40 Atoms in an Optical Fiber Cavity
TL;DR: Using atom chips and fiber-optical cavities, a method based on nondestructive collective measurement and conditional evolution is developed to create symmetric entangled states and perform their tomography, which demonstrates creation and analysis of entangled states with mean atom numbers up to 41 and experimentally prove multiparticle entanglement.
