摘要:

我们使用由Mobius畴壁实现构造的四维有效算符计算QCD Dirac算符的谱函数。我们利用本征值滤波技术结合随机估计的模式数。整个本征值范围内的频谱是用单组测量获得的。给出了格距为0.08 fm的Mobius畴壁海夸克2+1味系综的结果。

英文摘要:

We calculate the spectral function of the QCD Dirac operator using the four-dimensional effective operator constructed from the Mobius domain-wall implementation. We utilize the eigenvalue filtering technique combined with the stochastic estimate of the mode number. The spectrum in the entire eigenvalue range is obtained with a single set of measurements. Results on 2+1-flavor ensembles with Mobius domain-wall sea quarks at lattice spacing ~ 0.08 fm are shown.
