格点Schwinger模型中〈φφ〉的变分计算

Variational Study of 〈φφ〉 in the Lattice Schwinger Model

本文利用格点规范理论的变分方法,计算Schwinger模型中Naive格点费米子的真空凝聚参数〈φφ〉,得到较好的标度行为。

We used the variational method in lattice gauge theory to calculate the fermion condensate 〈φ,φ〉of the naive fermions in the Schwinger model, and obtained a nice scaling behavior.
