时空与物质之间的耦合

Generalising the coupling between spacetime and matter

Sante Carloni

摘要:

我们探索的想法,物质和时空之间的耦合比爱因斯坦最初设想的更复杂。我们提出这种耦合在爱因斯坦场方程中以一种新的基本张量的形式出现。然后,我们表明,这个张量的引入可以解释黑暗的现象在广义相对论,保持弱场限制兼容的标准牛顿引力。同样的范式也可以应用于任何其他引力理论。作为一个例子,我们表明,在共形引力的情况下,广义耦合能够解决问题和引力部门之间的兼容性问题。

英文摘要:

We explore the idea that the coupling between matter and spacetime is more complex than the one originally envisioned by Einstein. We propose that such coupling takes the form of a new fundamental tensor in the Einstein field equations. We then show that the introduction of this tensor can account for dark phenomenology in General Relativity, maintaining a weak field limit compatible with standard Newtonian gravitation. The same paradigm can be applied any other theory of gravitation. We show, as an example, that in the context of conformal gravity a generalised coupling is able to solve compatibility issues between the matter and the gravitational sector.
