格点量子色动力学的算法:进展与挑战

Algorithms for lattice QCD: progress and challenges

Stefan Schaefer

摘要:

改进的格点QCD算法的发展使我们能够在小夸克质量下进行计算,并控制手征外推。更精细的晶格也成为可能,然而,与规范场的拓扑结构相关的严重减速已经被观察到。这可能会阻止模拟足够精细的晶格来控制连续外推。本次会议的贡献介绍了当代晶格算法背后的基本概念,目前的知识,他们放缓对连续和未来的晶格模拟的后果。

英文摘要:

The development of improved algorithms for QCD on the lattice has enabled us to do calculations at small quark masses and get control over the chiral extrapolation. Also finer lattices have become possible, however, a severe slowing down associated with the topology of the gauge fields has been observed. This may prevent simulations of lattices fine enough for controlling the continuum extrapolation. This conference contribution introduces the basic concepts behind contemporary lattice algorithms, the current knowledge about their slowing down towards the continuum and its consequences for future lattice simulations.
