After investigating Landau levels and magneto-optical response of nodal line semimetals detailedly, we find that the Landau levels structures are ample when the magnetic field is present. The Landau levels are gapless and staggered corresponding to special magnetic field strength. In the presence of the double peaks derived from the transition between the staggered Landau levels, the background of magneto-optical conductivity is flat. We also study the effects of magnetic field intensity and chemical potential for magneto-optical response of transition between normal Landau levels.

节点线半金属的磁光导率

在详细研究了朗道能级和节点线半金属的磁光响应之后，我们发现当存在磁场时，朗道能级结构是足够的。兰道能级是无间隙且交错的，对应于特殊的磁场强度。在存在由交错的兰道能级之间的跃迁引起的双峰的情况下，磁光导率的背景是平坦的。我们还研究了磁场强度和化学势对正常Landau水平之间跃迁的磁光响应的影响。
