Correlations of Bose fireworks emission from strongly driven Bose-Einstein condensates.

ORAL

Abstract

Bose-Einstein condensates with oscillating interactions enables exciting opportunities to study~far from equilibrium~dynamics in quantum many-body~physics. Based on a fast modulation of magnetic field near a Feshbach resonance, we observe high harmonic generation~of matter-wave jets~from cesium~condensates.~The quantization of energy and momentum of atoms in the jets results from the Bose stimulation.~With the assistance of pattern recognition, we are able to identify~various scattering processes that leads to the pattern,~further confirmed by~correlation analysis. We also observe intricate high-order correlations~which can not be fully decomposed to lower order correlations.~Our observation can be modeled based on the hierarchy of inelastic collisions between atoms in the driven condensate.
