格点量子色动力学中的Berry相

Berry phase in lattice QCD

Arata Yamamoto

摘要:

提出了用格点量子色动力学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,我们用蒙特卡罗模拟计算了(2+1)维Wilson费米子的第一Chern数。

英文摘要:

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 (2+1)-dimensional Wilson fermion is calculated by the Monte Carlo simulation.
