论文摘要
由玻色子组成的超轻质暗物质的一个关键特征是在银河尺度上形成了超流体玻璃纤维冷凝物(BEC)结构。我们研究了GROSS-PITAEVSKII-POISSON模型框架中BEC孤子和涡流结构的碰撞。发现骨骼暗物质的超流体性质导致形成量化的涡旋线和在碰撞过程中形成的干扰模式中的量化涡流和涡流环。计算重力波光度,我们证明了量子干扰模式显着影响重力波辐射。 我们透露,超级流体自我修剪的BEC可以形成稳定的局部涡旋结构,即使在正面碰撞后,它们仍然保持稳健。
A key feature of ultra-light dark matter composed by bosons is the formation of superfluid Bose-Einstein condensate (BEC) structures on galactic scales. We study collisions of BEC solitonic and vortex structures in the framework of the Gross-Pitaevskii-Poisson model. It is found that the superfluid nature of bosonic dark matter leads to the formation of quantized vortex lines and vortex rings in interference patterns formed during collisions. Calculating the gravitational wave luminosity, we demonstrated that quantum interference patterns affect notably the gravitational wave radiation. We reveal that superfluid self-gravitating BECs can form stable localized vortex structures which remain robust even after a head-on collision.
