Bose Fireworks 2.0.

Abstract

When the scattering length of a Bose-Einstein condensate is periodically modulated, atoms in the condensate can form numerous jets emitting in all directions, resembling fireworks. With an increasing modulation strength, we observe a high-order harmonic generation of matter-waves where emitted atoms form a multi-ring structure with quantized energy and momentum. Based on the evolution dynamics, we find that atoms in the high order rings originate from multiple scattering processes.~With the assistance of~pattern recognition, we identify a unique 10-jet pattern in the emission that reveals intricate correlations between atomic populations in different momentum modes. We propose that the jet pattern is a result of Bose stimulation of secondary collisions into modes with macroscopic population.
