Measuring and engineering entropy and spin squeezing in weakly linked Bose-Einstein condensates
F. Cattani, C. Gross, M. K. Oberthaler +1
We propose a method to infer the single-particle entropy of bosonic atoms in an optical lattice and to study the local evolution of entropy, spin squeezing, and entropic inequaliti…
Atomic homodyne detection of continuous variable entangled twin-atom states
C. Gross, H. Strobel, E. Nicklas +4
Historically, the completeness of quantum theory has been questioned using the concept of bipartite continuous variable entanglement. The non-classical correlations (entanglement)…
Rabi flopping induces spatial demixing dynamics
E. Nicklas, H. Strobel, T. Zibold +4
We experimentally investigate the mixing/demixing dynamics of Bose-Einstein condensates in the presence of a linear coupling between two internal states. The observed amplitude red…
EPR entanglement strategies in two-well BEC
Q. Y. He, M. D. Reid, C. Gross +2
Criteria suitable for measuring entanglement between two different potential wells in a Bose- Einstein condensation (BEC) are evaluated. We show how to generate the required entang…
Local and spatially extended sub-Poisson atom number fluctuations in optical lattices
C. Gross, J. Esteve, M. K. Oberthaler +2
We demonstrate that ultracold interacting bosonic atoms in an optical lattice show sub-Poissonian on-site and inter-site atom number fluctuations. The experimental observations agr…
Multiple atomic dark solitons in cigar-shaped Bose-Einstein condensates
G. Theocharis, A. Weller, J. P. Ronzheimer +4
We consider the stability and dynamics of multiple dark solitons in cigar-shaped Bose-Einstein condensates (BECs). Our study is motivated by the fact that multiple matter-wave dark…
