标题： Gauge Singularities in the SU(2) Vacuum on the Lattice

摘要： 由威尔逊作用量生成的SU(2)配置被转换为朗道规范，并通过傅里叶滤波进行平滑。 这导致场强及相关量出现尖锐峰值。 这些尖峰是由规范奇点引起的。 其密度确定为每fm**4有1.5个尖峰，并与弦张力成比例。 当接近禁闭区域时，尖峰数量趋于零。 研究了尖峰与格里博夫副本、冷却作用量极大值以及胶子传播函数的相关性。 显示英文摘要

摘要： SU(2) configurations, which have been generated by the Wilson action, are transformed to a Landau gauge and smoothed by Fourier filtering. This leads to sharp peaks in the field strengths and in related quantities. These spikes are caused by gauge singularities. Their density is determined as 1.5 spikes per fm**4, and it scales with the string tension. The number of spikes vanishes when approaching the deconfinement regions. Correlations of spikes with Gribov copies, with cooled action maxima and with the gluon propagator are studied.
