Bose fireworks

Experiments frequently come with surprises. In this talk, I will describe a serendipitous discovery of Bose fireworks, the sudden emission of many narrow jets of matterwaves from Bose-Einstein condensates with oscillating interaction strength. This structure originates from a collective scattering of atoms in the condensate, seeded by quantum fluctuations and amplified by bosonic stimulation. The process is the matterwave version of superradiance, and results in an intriguing di-jet pattern resembling those observed in high-energy collisions of heavy ions.
