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.
