具有电磁相互作用的弯曲时空中玻色-爱因斯坦凝聚体的协变理论:流体动力学方法

Covariant theory of Bose-Einstein condensates in curved spacetimes with electromagnetic interactions: the hydrodynamic approach

Pierre-Henri Chavanis, Tonatiuh Matos

摘要:

我们开发了一个流体动力学表示的Klein-Gordon-Maxwell-Einstein方程。这些方程结合了量子力学、电磁学和广义相对论。我们考虑任意弯曲时空的情形,静态或膨胀背景中弱引力场的情形,以及非相对论性(牛顿)极限。克莱因-戈登-麦克斯韦-爱因斯坦方程控制着复杂标量场的演化,可能描述了耦合到电磁场的自引力玻色-爱因斯坦凝聚体。他们可能会在暗物质、玻色子星和具有超流核的中子星的背景下找到应用。

英文摘要:

We develop a hydrodynamic representation of the Klein-Gordon-Maxwell-Einstein equations. These equations combine quantum mechanics, electromagnetism, and general relativity. We consider the case of an arbitrary curved spacetime, the case of weak gravitational fields in a static or expanding background, and the nonrelativistic (Newtonian) limit. The Klein-Gordon-Maxwell-Einstein equations govern the evolution of a complex scalar field, possibly describing self-gravitating Bose-Einstein condensates, coupled to an electromagnetic field. They may find applications in the context of dark matter, boson stars, and neutron stars with a superfluid core.
