格点费米子规范重整化群变换

On Gauged Renormalisation Group Transformations of Lattice Fermions

Artan Borici

摘要:

我们构造了一个格费米子的层次结构,其中较粗的格狄拉克算子是较细的格算子的块UL分解的Schur补。我们表明,建设是一个确切的规范重整化群变换的晶格作用。特别是,使用这样的变换和QCDLAB工具,它示出了如何实现的Ginsparg-Wilson策略的手征费米子中存在的动态规范场。该计划允许,第一次,一个完整的多重网格算法格夸克。

英文摘要:

We construct a hierarchy of lattice fermions, where the coarser lattice Dirac operator is the Schur complement of the block UL decomposition of the finer lattice operator. We show that the construction is an exact gauged renormalisation group transformation of the lattice action. In particular, using such a transformation and the QCDLAB tool, it is shown how to implement the Ginsparg-Wilson strategy for chiral fermions in the presence of a dynamical gauge field. The scheme allows, for the first time, a full multigrid algorithm for lattice quarks.
