摘　　要：从非惯性系中的拉格朗日函数出发,通过求解哈密顿量引出了带电粒子在电磁场中规范势的概念.解析了冷原子体系在旋转坐标系和非均匀磁场中产生人造规范势的原理,并阐述了人造规范场在凝聚态物理中的重要应用,如涡旋的产生和量子霍尔效应.Starting from the Lagrange function in the noninertial system,the concept of the gauge potential of charged particles in the electromagnetic field is derived by solving the Hamiltonian.By discussing the Hamiltonian analytically of neutral atoms in rotation ratame and in a nonuniform magnetic field,the principle of artificial potentials are introduced.The important applications of artificial gauge field in condensed matter physics such as quantized vortex and Hall effect is mainly elaborated subsequently.
