Squeezing and entanglement in a Bose-Einstein condensate
J. Esteve, C. Gross, A. Weller +2
Entanglement, a key feature of quantum mechanics, is a resource that allows the improvement of precision measurements beyond the conventional bound reachable by classical means. Th…
Spontaneous symmetry breaking of gap solitons in double-well traps
M. Trippenbach, E. Infeld, J. Gocalek +3
We introduce a two dimensional model for the Bose-Einstein condensate with both attractive and repulsive nonlinearities. We assume a combination of a double well potential in one d…
Dark matter-wave solitons in the dimensionality crossover
G. Theocharis, P. G. Kevrekidis, M. K. Oberthaler +1
We consider the statics and dynamics of dark matter-wave solitons in the dimensionality crossover regime from 3D to 1D. There, using the nonpolynomial Schrödinger mean-field model,…
A Primary Noise Thermometer for Ultracold Bose Gases
R. Gati, J. Esteve, B. Hemmerling +4
We discuss in detail the experimental investigation of thermally induced fluctuations of the relative phase between two weakly coupled Bose-Einstein condensates. In analogy to supe…
Realization of a single Josephson junction for Bose-Einstein condensates
Rudolf Gati, Micheal Albiez, Jonas Foelling +2
We report on the realization of a double-well potential for Rubidium-87 Bose-Einstein condensates. The experimental setup allows the investigation of two different dynamical phenom…
Noise Thermometry with Two Weakly Coupled Bose-Einstein Condensates
Rudolf Gati, Boerge Hemmerling, Jonas Foelling +2
Here we report on the experimental investigation of thermally induced fluctuations of the relative phase between two Bose-Einstein condensates which are coupled via tunneling. The…
