The unexpected Bose fireworks
Experiments frequently 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 driven Bose-Einstein condensate. The jet emission originates from collective scattering of atoms, seeded by quantum fluctuations and amplified by bosonic stimulation. The process results in an intricate jet emission pattern resembling those observed in high-energy collisions of heavy ions as well as Unruh radiation near the event horizon. It also offers us new insight to understand spontaneous pattern formation and molecular Bose-Einstein condensate. I will describe the intriguing journey we have had and future goals associated with the Bose fireworks.
