Tunable source of correlated atom beams
Marie Bonneau, Josselin Ruaudel, Raphaël Lopes +4
We use a one-dimensional optical lattice to modify the dispersion relation of atomic matter waves. Four-wave mixing in this situation produces atom pairs in two well defined beams.…
An acoustic analog to the dynamical Casimir effect in a Bose-Einstein condensate
Jean-Christophe Jaskula, Guthrie B. Partridge, Marie Bonneau +4
We have realized an acoustic analog to the Dynamical Casimir effect. The density of a trapped Bose-Einstein condensate is modulated by changing the trap stiffness. We observe the c…
Violation of the Cauchy-Schwarz inequality with matter waves
K. V. Kheruntsyan, J. -C. Jaskula, P. Deuar +6
The Cauchy-Schwarz (CS) inequality -- one of the most widely used and important inequalities in mathematics -- can be formulated as an upper bound to the strength of correlations b…
