基于格点模拟的双味Schwinger模型的新认识

New insight in the 2-flavor Schwinger model based on lattice simulations

Jaime Fabián Nieto Castellanos, Wolfgang Bietenholz, Ivan Hip

摘要:

我们考虑Schwinger模型与两个简并,轻费米子口味的格子模拟。在有限的温度下,我们探测的玻色子化方法的可行性细谷等人。接下来,我们探索一个类似的π介子衰变常数,同意独立的配方的基础上的盖尔曼-奥克斯-伦纳关系,2维威滕-Veneziano公式和$δ$制度。最后我们用晶格结果讨论了手征凝聚体的几个性质。

英文摘要:

We consider the Schwinger model with two degenerate, light fermion flavors by means of lattice simulations. At finite temperature, we probe the viability of a bosonization method by Hosotani et al. Next we explore an analogue to the pion decay constant, which agrees for independent formulations based on the Gell-Mann--Oakes--Renner relation, the 2-dimensional Witten--Veneziano formula and the $δ$-regime. Finally we confront several conjectures about the chiral condensate with lattice results.
