格点量子色动力学中费米子行列式的四维因式分解

Four-dimensional factorization of the fermion determinant in lattice QCD

Leonardo Giusti, Matteo Saccardi

摘要:

最近几年,有人提出了在具有Wilson型费米子的格点量子色动力学中,费米子行列式的一维因式分解,从而导致了辅助玻色子场的块局域作用量。在这里,我们提出了一个四维推广的这种分解。可能的应用是更有效的并行化的蒙特卡罗算法和代码,主场模拟,和多级集成。

英文摘要:

In the last few years it has been proposed a one-dimensional factorization of the fermion determinant in lattice QCD with Wilson-type fermions that leads to a block-local action of the auxiliary bosonic fields. Here we propose a four-dimensional generalization of this factorization. Possible applications are more efficient parallelizations of Monte Carlo algorithms and codes, master field simulations, and multi-level integration.
