非对易空间谱Action的量子引力边界项

Quantum Gravity Boundary Terms from Spectral Action of Noncommutative Space

Ali H. Chamseddine, Alain Connes

摘要:

我们研究了非对易空间的谱作用量的边界项,它是由标准模型的物理谱决定的谱三元组定义的,把引力与所有其他基本相互作用统一起来。我们证明了谱作用量以正确的符号和系数唯一地预测了量子引力一致性所需的引力边界项。这是一个值得注意的结果,因为在光谱作用中缺乏自由来调谐这项。

英文摘要:

We study the boundary terms of the spectral action of the noncommutative space, defined by the spectral triple dictated by the physical spectrum of the standard model, unifying gravity with all other fundamental interactions. We prove that the spectral action predicts uniquely the gravitational boundary term required for consistency of quantum gravity with the correct sign and coefficient. This is a remarkable result given the lack of freedom in the spectral action to tune this term.
