论文摘要
手稿处理一个相互作用的标量场，该标量场模仿了所谓的轴突标量暗物质或轴，例如具有超光质量的颗粒。讨论的是，这种标量与普通的流体描述可以在强力较大的情况下崩溃。塌陷的末端状态取决于轴突如何与几何和普通物质相互作用。对于自我相互作用的轴和与几何相互作用的轴，塌陷可能导致零量的奇异性或弹跳和轴的总分布。但是，对于与普通流体描述相互作用的轴，没有奇异性的形成，并且轴支球场在辐射到零值之前表现出周期性的行为。通常，这种崩溃和散布伴随着违反无效的能量条件。
The manuscript deals with an interacting scalar field that mimics the evolution of the so-called Axion Scalar Dark Matter or Axion like particles with ultra-light masses. It is discussed that such a scalar alongwith an ordinary fluid description can collapse under strong gravity. The end state of the collapse depends on how the Axion interacts with geometry and ordinary matter. For a self-interacting Axion and an Axion interacting with geometry the collapse may lead to a zero proper volume singularity or a bounce and total dispersal of the Axion. However, for an Axion interacting with the ordinary fluid description, there is no formation of singularity and the Axion field exhibits periodic behavior before radiating away to zero value. Usually this collapse and dispersal is accompanied by a violation of the Null Energy Condition.
