我们利用晶格QCD蒙特卡罗模拟研究了SU (3) QCD在最大阿贝尔(MA)规范中夸克约束的对偶超导体图中的自发手性对称性破缺,在β= 6.0(即间距a≃0.1 fm)和32⁴at β= 6.2(即间距a≃0.075 fm)的四个不同晶格在淬灭水平上分别为16⁴、24⁴、24³× 6。首先,在约束阶段,我们使用两种不同的方法(i)基于Dirac特征值密度的Banks-Casher关系和(ii)基于夸克传播子及其手性外推的有限夸克-质量计算,在手性极限的手性凝聚的MA规范中发现了Abelian优势和单极子优势。在高温限定相中,也观察到阿贝尔扇区和单极扇区的手性恢复。其次,我们研究了手性凝聚态与磁单极子之间的局部相关性。我们发现手性凝聚在单极子附近的局部值相当大。作为一种有趣的可能性,单极子周围的强磁场是QCD中手性对称性破缺的原因,类似于磁催化。
We study spontaneous chiral-symmetry breaking in SU (3) QCD in terms of the dual superconductor picture for quark confinement in the maximally Abelian (MA) gauge, using lattice QCD Monte Carlo simulations with four different lattices of 16⁴, 24⁴, 24³× 6 at β= 6.0 (ie, the spacing a≃ 0.1 fm), and 32⁴ at β= 6.2 (ie, a≃ 0.075 fm), at the quenched level. First, in the confinement phase, we find Abelian dominance and monopole dominance in the MA gauge for the chiral condensate in the chiral limit, using the two different methods of (i) the Banks-Casher relation with the Dirac eigenvalue density and (ii) finite quark-mass calculations with the quark propagator and its chiral extrapolation. In the high-temperature deconfined phase, the chiral restoration is observed also for the Abelian and the monopole sectors. Second, we investigate local correlation between the chiral condensate and monopoles, which topologically appear in the MA gauge. We find that the chiral condensate locally takes a quite large value near monopoles. As an interesting possibility, the strong magnetic field around monopoles is responsible to chiral symmetry breaking in QCD, similarly to the magnetic catalysis.
