归一化超三次涂抹中位错的抑制
Suppressing dislocations in normalized hypercubic smearing
摘要：
规范化超立方涂抹改善了动态威尔逊-三叶草费米子的行为，但有不必要的副作用，它偶尔会产生费米子力的尖峰。这些尖峰起源于链式法则，该链式法则将相对于涂抹链接的导数连接到相对于动态链接的导数，并且与动态规范场中位错的存在相关联。我们提出并研究了旨在抑制这些位错的行动。我们提出了证据的混合蒙特卡罗算法的性能改善。一个附带的好处是价手征费米子的性质得到了改善。
英文摘要：
Normalized hypercubic smearing improves the behavior of dynamical Wilson-clover fermions, but has the unwanted side effect that it can occasionally produce spikes in the fermion force. These spikes originate in the chain rule connecting the derivative with respect to the smeared links to the derivative with respect to the dynamical links, and are associated with the presence of dislocations in the dynamical gauge field. We propose and study an action designed to suppress these dislocations. We present evidence for improved performance of the hybrid Monte Carlo algorithm. A side benefit is improvement in the properties of valence chiral fermions.
