论文摘要
来自晶格计算的充分数值证据表明,在有限温度下仪表理论的狭窄特性与低较低狄拉克本特征模型的定位特性之间存在牢固的联系。在这项贡献中,我们讨论了该主题的最新进展,重点关注QCD在假想的化学势$μ_i/t =π$上,在Roberge-Weiss过渡温度上方的温度下。这些证实了在解元转换处的低模式的一般图片,从异式的设置中,在存在动态费米子的情况下,在脱浓度的转变处转向局部。这进一步支持使用Dirac eigenmodes作为研究限制和解次转换的机制的工具。
Ample numerical evidence from lattice calculations shows a strong connection between the confining properties of gauge theories at finite temperature and the localisation properties of the low-lying Dirac eigenmodes. In this contribution we discuss recent progress on this topic, focussing on results for QCD at imaginary chemical potential $μ_I/T = π$ at temperatures above the Roberge-Weiss transition temperature. These confirm the general picture of low modes turning from delocalised to localised at the deconfinement transition, in a previously unexplored setup with a genuine, physical transition in the presence of dynamical fermions. This further supports the use of Dirac eigenmodes as a tool to investigate the mechanisms behind confinement and the deconfinement transition.
