Emission of twin jets from a driven matter-wave soliton in a quasi-one-dimensional geometry.

The modulation of the interaction between the atoms in a matter-wave soliton in a quasi-one-dimensional optical trap triggers an emission of correlated atom jets. We characterize the dependence of jet properties on the frequency, amplitude and length of the modulation, and qualitatively reproduce the trends in the mean-field picture with a one-dimensional time-dependent Gross-Pitaevskii equation simulation. High-order jets are observed for sufficiently long pulses, a double-pulse modulation sequence produces consecutive jets, and a multi-pulse sequence may lead to irregular jets at a finite angle to the direction of the channel. Finally, possible number squeezing of the jet pairs is investigated.
