摘要翻译:
我们构造了一个晶格费米子族,其中较粗的晶格Dirac算子是较细的晶格算子的块UL分解的Schur补。我们证明了该构造是晶格作用的精确度量重整化群变换。特别地,利用这种变换和QCDLAB工具,说明了如何在动力学规范场中实现手征费米子的Ginsparg-Wilson策略。该方案首次为晶格夸克提供了一个完整的多重网格算法。

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.
