导出了具有两个Weyl费米子的相对论性物质在电磁场和伪电磁场中精确到二阶的一致手性动力学理论。利用这一框架，研究了纵向集体激励的性质，包括手性磁波和手性伪磁波。结果表明，适当的动态电磁学处理可将这些无间隙波转化为手性（伪）磁等离子体，其朗缪尔（等离子体）间隙在磁场和伪磁场中均得到二次修正。
The consistent chiral kinetic theory accurate to the second order in electromagnetic and pseudoelectromagnetic fields is derived for a relativistic matter with two Weyl fermions. By making use of such a framework, the properties of longitudinal collective excitations, which include both chiral magnetic and chiral pseudomagnetic waves, are studied. It is shown that the proper treatment of dynamical electromagnetism transforms these gapless waves into chiral (pseudo)magnetic plasmons, whose Langmuir (plasma) gap receives corrections quadratic in both magnetic and pseudomagnetic fields.
