Our paper, "Collective emission of matter-wave jets from driven Bose-Einstein condensates" is published in Nature

We report an exciting observation that a rapid modulation of the interactions between atoms in a Bose-Einstein condensate leads to emission of atoms that forms jet structure. In the figure, the image on the far left is the original condensate, 15 micron in diameter. The 4 images on the right show the evolution of the sample during the emission process of about 20 ms.
