论文摘要
Using 10-16 units of Nvidia DGX-1, we have generated the first gauge ensemble for $N_f=2+1+1$ lattice QCD with physical $(u/d, s, c)$ domain-wall quarks, on the $ 64^4 $ lattice with lattice spacing $a \sim 0.064 $ fm ($ L > 4 $ fm, and $ M_πL > 3 $).该规格集合的显着特征是,手性对称性被保存至高精度,所有拓扑扇区均以态度采样。在本文中,我们介绍了拓扑敏感性和地下强子质谱的第一个结果。
Using 10-16 units of Nvidia DGX-1, we have generated the first gauge ensemble for $N_f=2+1+1$ lattice QCD with physical $(u/d, s, c)$ domain-wall quarks, on the $ 64^4 $ lattice with lattice spacing $a \sim 0.064 $ fm ($ L > 4 $ fm, and $ M_πL > 3 $). The salient feature of this gauge ensemble is that the chiral symmetry is preserved to a high precision and all topological sectors are sampled ergodically. In this paper, we present the first results of the topological susceptibility and the ground-state hadron mass spectra.
