论文摘要

我们引入了通常的真空能的概括,称为“变形真空能”,该真空能产生各向异性压力,同时保留零惯性质量密度。它以独特的方式将剪切标量耦合到剪切标量,从而使它们具有任意潜力的规范标量场。这通过基于规范标量字段的重新考虑宇宙学来开辟新的途径,并获得一个奖励,即标量场的动力学术语被可观察到的剪切标量替换。我们进一步阐述了这种方法在黑暗能源的背景下。

We introduce a generalization of the usual vacuum energy, called `deformed vacuum energy', which yields anisotropic pressure whilst preserving zero inertial mass density. It couples to the shear scalar in a unique way, such that they together emulate the canonical scalar field with an arbitrary potential. This opens up a new avenue by reconsidering cosmologies based on canonical scalar fields, along with a bonus that the kinetic term of the scalar field is replaced by an observable, the shear scalar. We further elaborate the aspects of this approach in the context of dark energy.
