玻色-爱因斯坦凝聚冷暗物质晕中的涡旋和Angular Momentum

Vortices and Angular Momentum in Bose-Einstein-Condensed Cold Dark Matter Halos

Tanja Rindler-Daller, Paul R. Shapiro

摘要:

如果冷的暗物质基本粒子形成玻色-爱因斯坦凝聚体,它们的超流性可能将它们与其他形式的冷暗物质区分开来,包括量子涡旋的产生。我们在这里证明,这样的旋涡是有利的强耦合凝聚,而这不是轴子的情况下,这通常被认为是形成一个玻色-爱因斯坦凝聚体,但实际上是非相互作用。

英文摘要:

If cold dark matter elementary particles form a Bose-Einstein condensate, their superfluidity may distinguish them from other forms of cold dark matter, including creation of quantum vortices. We demonstrate here that such vortices are favoured in strongly-coupled condensates, while this is not the case for axions, which are generally presumed to form a Bose-Einstein condensate but are effectively non-interacting.
