To the recorded seminar:

Experiments come with surprises. In this talk, I will describe the story behind the discovery of Bose fireworks, a sudden emission of matterwave jets from  a periodic Bose-Einstein condensate. The jet emission originates from collective inelastic scattering of atoms, seeded by quantum fluctuations. The process results in an intricate jet emission pattern resembling those observed in high-energy collisions of heavy ions as well as Hawking-Unruh radiation near the event horizon. It also offers us new insight to understand quantum pattern formation and molecular Bose condensate. I will describe the intriguing journey we have had and new ideas motivated by this observation.
