我们提出了用格点QCD方法计算由单个费米子基态定义的Berry相。我们进行基态投影的单费米子传播，构造的Berry链接变量的动量空间晶格，并计算Berry相位。作为第一个应用，我们用Monte Carlo方法计算了（）维Wilson费米子的第一Chern数。
We propose the lattice QCD calculation of the Berry phase, which is defined by the ground state of a single fermion. We perform the ground-state projection of a single-fermion propagator, construct the Berry link variable on a momentum-space lattice, and calculate the Berry phase. As the first application, the first Chern number of the ()-dimensional Wilson fermion is calculated by the Monte Carlo simulation.
