  • Abstract摘要
    Bose-Bose droplets are self-bound systems stabilized by quantum fluctuations. They can be formed in a mixture of two Bose-Einstein condensates when mutual  interactions of atoms are properly tuned. The droplets are the most dilute fluids ever. Their  density is about eight orders of magnitude smaller than density of a typical  liquid.
    Starting from  basic properties of atomic Bose-Einstein condensates,  I will  describe a mechanism of formation of such  droplets. Then I will discuss  results of our numerical studies of low energy collisions of two-component  droplets. I will show that relative phases of droplet’s wave-functions  determine  a scenario of the process. I will argue that the collisions can be understood in terms of  Josephson junction physics.
