三味量子色动力学系统在强平行电磁场下的U_A(1)量子反常

这个项目，我希望把之前两味量子色动力学（QCD）系统在平行电磁场下的研究拓展到三味情形，从而更接近于实际地去研究QCD系统的基态以及对应的集体激发模式发生的变化， 特别是U_A (1)量子反常效应所起的作用。除此之外，我们还将引入作为禁闭与解禁闭相变序参量的Polyakov圈，以便进一步理清平行电磁场导致的U_A (1)量子反常对禁闭性质的影响。

In this project, I extend the previous study of two-flavor quantum chromodynamics (QCD) system under parallel electromagnetic (EM) field to the case with three flavor. In this way, we can more realistically explore the shifting of the ground state of QCD system and the corresponding collective excitation modes, especially induced by U_A (1) quantum anomaly effect. Besides, we will introduce Polyakov loop which is the order parameter of the confinement and deconfinement transition，and clarify how the confinement property is affected by the U_A (1) quantum anomaly which is induced by parallel EM field.
