Yang-Mills流线与半经典禁闭

Yang-Mills streamlines and semi-classical confinement

Kurt Langfeld, Ernst-Michael Ilgenfritz

摘要:

杨-米尔斯理论中的半经典组态是利用最近提出的约束冷却技术从格点蒙特卡罗组态中导出的,该技术旨在保持每一条Polyakov线(在时空中的任何点,任何方向)。因此,禁闭被发现维持的合奏半经典配置。胶子和费米子近零模的存在被证明是在冷却组态周围可能的半经典膨胀的先决条件,同时也提供了手征对称性破缺所必需的狄拉克算符的无隙谱。分析了半经典流线构型的拓扑荷的簇结构,并表明其支持正确大小的轴向异常,尽管其结构不同于瞬子气体或液体。在这里,我们提出了进一步的细节的时空结构和时间演化的流线配置。

英文摘要:

Semi-classical configurations in Yang-Mills theory have been derived from lattice Monte Carlo configurations using a recently proposed constrained cooling technique which is designed to preserve every Polyakov line (at any point in space-time in any direction). Consequently, confinement was found sustained by the ensemble of semi-classical configurations. The existence of gluonic and fermionic near-to-zero modes was demonstrated as a precondition for a possible semi-classical expansion around the cooled configurations as well as providing the gapless spectrum of the Dirac operator necessary for chiral symmetry breaking. The cluster structure of topological charge of the semi-classical streamline configurations was analysed and shown to support the axial anomaly of the right size, although the structure differs from the instanton gas or liquid. Here, we present further details on the space-time structure and the time evolution of the streamline configurations.
