格点上的量子标度不变性

Quantum scale invariance on the lattice

Mikhail E. Shaposhnikov, Igor I. Tkachev

摘要:

我们提出了一个方案,导致一个非微扰的定义格场论的尺度不变的量子水平。该结构的一个关键思想是用一个传播的动力场--声子来代替晶格间距。我们描述了如何选择非微扰的唯象可行的理论,尺度不变性是自发打破。还讨论了与重力的关系。

英文摘要:

We propose a scheme leading to a non-perturbative definition of lattice field theories which are scale-invariant on the quantum level. A key idea of the construction is the replacement of the lattice spacing by a propagating dynamical field -- the dilaton. We describe how to select non-perturbatively the phenomenologically viable theories where the scale invariance is broken spontaneously. Relation to gravity is also discussed.
