BV quantization of dynamical fuzzy spectral triples

James Gaunt, Hans Nguyen, Alexander Schenkel

摘要:

本文系统地研究了Barrett等人提出的量子引力动力学模糊谱三重模型中的规范对称性。我们开发的经典和微扰量子BV形式主义这些模型,特别是导致一个明确的同调结构的微扰量子关联函数。我们发现,鬼和反场的贡献,这样的关联函数的相关性强烈依赖于背景狄拉克运营商$D_0$周围的一个扰动,特别是对数量的规范对称性,它打破。这将通过研究1附近的量子微扰来说明。)一般$(p,q)$模型中规范不变的零狄拉克算子$D_0=0$; 2.)四次$(0,1)$模型中的非平凡$D_0$的简单示例。

英文摘要:

This paper provides a systematic study of gauge symmetries in the dynamical fuzzy spectral triple models for quantum gravity that have been proposed by Barrett and collaborators. We develop both the classical and the perturbative quantum BV formalism for these models, which in particular leads to an explicit homological construction of the perturbative quantum correlation functions. We show that the relevance of ghost and antifield contributions to such correlation functions depends strongly on the background Dirac operator $D_0$ around which one perturbs, and in particular on the amount of gauge symmetry that it breaks. This will be illustrated by studying quantum perturbations around 1.) the gauge-invariant zero Dirac operator $D_0=0$ in a general $(p,q)$-model, and 2.) a simple example of a non-trivial $D_0$ in the quartic $(0,1)$-model.
