玻色子星与振荡子

Boson Stars and Oscillatons: A Review

Luca Visinelli

摘要:

紧凑型物体在自然探索中占据着举足轻重的地位。兴趣范围从天体物理学中致密天体的作用到通过各种方法(引力波干涉测量法、微透镜、成像)对其进行探测。虽然由费米子(中子星和白矮星)组成的紧凑物体的存在已经得到了评估,但对由玻色子组成的局部孤子的平行搜索正在进行中,源于惠勒最初提出的电磁“geons”。玻色子场可以聚集并形成紧凑的物体,如玻色子星(对于复杂的标量场),玻色子和玻色子(对于真实的标量场),或Proca星(对于大质量矢量场),它们可以在搜索中显示为黑洞模仿者,暗物质源和各种其他现象。我回顾了这些玻色子系统的一些重要性质,包括该领域的最新进展。

英文摘要:

Compact objects occupy a pivotal role in the exploration of Nature. The interest spans from the role of compact objects in astrophysics to their detection through various methods (gravitational waves interferometry, microlensing, imaging). While the existence of compact objects made of fermions (neutron stars and white dwarfs) has been assessed, a parallel search for localized solitons made of bosons is ongoing, stemming from Wheeler's original proposal of electromagnetic "geons". Boson fields can clump up and form compact objects such as boson stars (for complex scalar fields), oscillons and oscillatons (for real scalar fields), or Proca stars (for massive vector fields), which can show up in searches as black hole mimickers, dark matter sources, and a variety of other phenomena. I review some crucial properties of these bosonic systems, including recent progress in the field.
