Danai Roumelioti, Stelios Stefas, George Zoupanos

AI总结:

本研究扩展了协变非对易空间的描述,通过扩大等距同构群构建出德西特与反德西特空间下的两个模糊引力模型,还首次探讨了该引力框架中费米子的引入及与$SO(10)$/$SU(5)$大统一内部相互作用的统一。

摘要:

在本工作中,我们对协变非对易空间进行了扩展描述,该空间可容纳此前构建的Fuzzy Gravity(模糊引力)模型。研究基于如下历史经验:使用包含连续空间等距同构所有生成元的更大代数,有助于构建模糊协变非对易空间。具体而言,对等距同构群的进一步扩展,除了让我们构建出协变非对易空间,还提出了为构建模糊引力理论需在该空间上进行规范的群。最终,我们根据等距同构群的扩展方式,得到了两个模糊引力模型,分别位于de Sitter(德西特)空间和anti-de Sitter(反德西特)空间中,并讨论了它们的自发对称性破缺,这一破缺会产生非对易$SO(1,3)$引力的模糊版本。此外,我们首次讨论了如何在模糊引力中引入费米子,更重要的是,探讨了如何将构建的非对易-模糊引力与基于$SO(10)$或$SU(5)$大统一理论的内部相互作用相统一。

英文摘要:

In the present work we present an extended description of the covariant noncommutative space, which accommodates the Fuzzy Gravity model constructed previously. It is based on the historical lesson that the use of larger algebras containing all generators of the isometry of the continuous one helped in formulating a fuzzy covariant noncommutative space. Specifically a further enlargement of the isometry group leads us, in addition to the construction of the covariant noncommutative space, also to the suggestion of the group that should be gauged on such a space in order to construct a Fuzzy Gravity theory. As a result, we obtain two Fuzzy Gravity models, one in de Sitter and one in anti-de Sitter space, depending on the extension of the isometry group, and we discuss their spontaneous symmetry breaking leading to fuzzy versions of the noncommutative $SO(1,3)$ gravity. In addition we discuss for the first time how to introduce fermions in the fuzzy gravity and even more importantly how to unify the constructed noncommutative-fuzzy gravity with internal interactions based on $SO(10)$ or $SU(5)$ as grand unified theories.
