Translation in Cylindrically Symmetric Vacuum

M. -N. Celerier, R. Chan, M. F. A. da Silva, N. O. Santos

摘要:

从静止圆柱对称解出发,但坐标$z$和$ϕ$互换,假设它可以描述平移圆柱的真空时空,研究它的物理和几何性质。这一假设并不完全是新的,因为它已经被认为是在以前的文件中描述的翻译来源。我们表明,这个度规是几何相关的真空场产生的一个固定的旋转圆柱源{,称为刘易斯解决方案。然而,我们发现了新的物理性质,不同于路易斯真空溶液。此外,我们还证明了在广义相对论中不可能存在平移圆柱尘埃解。

英文摘要:

Starting from the stationary cylindrically symmetric solution, but with the coordinates $z$ and $ϕ$ interchanged, and supposing that it could describe the vacuum spacetime of a translating cylinder, we investigate its physical and geometrical properties. This hypothesis is not entirely new since it has already been considered in a previous paper describing a translating source. We show that this metric is geometrically related to the vacuum field produced by a stationary rotating cylindrical source{, known as Lewis solution. However, we find new physical properties, different from those of the Lewis vacuum solution. Moreover, we show that no translating cylindrical dust solution can exist in General Relativity.
