从群论场论看四维变形狭义相对论

4d Deformed Special Relativity from Group Field Theories

Florian Girelli, Etera R. Livine, Daniele Oriti

摘要:

本文从定义四维时空中拓扑BF理论跃迁振幅的SO(4,1)群场论出发,导出了一个生活在非对易的Kappa-Minkowski时空中的具有Kappa变形庞加莱对称性的变形狭义相对论型标量场理论。这是在非微扰水平的自旋泡沫形式主义工作直接与集团场论(GFT)。我们表明,从基本模型出现的物质场作为扰动周围的GFT的一个特定的阶段,对应于一个解决方案的基本方程的运动,和非交换场论管理其有效的动态。

英文摘要:

We derive a scalar field theory of the deformed special relativity type, living on non-commutative kappa-Minkowski spacetime and with a kappa-deformed Poincare symmetry, from the SO(4,1) group field theory defining the transition amplitudes for topological BF-theory in 4 space-time dimensions. This is done at a non-perturbative level of the spin foam formalism working directly with the group field theory (GFT). We show that matter fields emerge from the fundamental model as perturbations around a specific phase of the GFT, corresponding to a solution of the fundamental equations of motion, and that the non-commutative field theory governs their effective dynamics.
