本文提出了一种通用的 stationary 轴对称度量形式,用于构建允许分离结构的旋转解,并展示了多个具体例子,包括带有全局单极的旋转黑洞和新型旋转虫洞几何。

摘要:

我们开发了一个系统框架,用于制定和求解导致 stationary 轴对称时空在存在物质场时可分离的条件。受 Carter 的度量形式引导,我们引入了一个通用的 stationary 轴对称度量假设,允许径向和角向变量的透明分离。这一构造产生了一族广泛的 stationary 旋转解,允许分离结构。为了说明该形式的适用性,我们显式地构造了几个例子,包括由各向异性物质支持的旋转黑洞以及一类新的旋转虫洞几何。

英文摘要:

We develop a systematic framework for formulating and solving the conditions that lead to separability in stationary, axisymmetric spacetimes in the presence of matter fields. Guided by Carter's metric form, we introduce a general stationary, axisymmetric metric ansatz that allows for a transparent separation of radial and angular variables. This construction yields a broad family of stationary rotating solutions admitting separability structures. To illustrate the applicability of the formalism, we explicitly construct several examples, including a rotating black hole with a global monopole supported by anisotropic matter, as well as a new class of rotating wormhole geometries.
