物质场 meaning in English
material field
Examples
- We disscuss the field theory in noncommutative space . the gauge invariance of noncommutative gauge field coupled with matter field is studied
我们讨论了非对易空间与规范场耦合的物质场的规范对称性。 - Then we in - vest gate seiberg - witten map , which defines the equivalence relation of the gauge symmetries in different spaces . we also analyse the u ( l ) gauge electromagnetic field in noncommutative space . finally we discuss the ambiguities of seiberg - witten map , and find although that some part of the ambiguities can be absorbed by gauge transformation and hence negligible , the existence of the matter field makes some other parts difficult to be absorbed by gauge transformation or field redefinition
然后利用seiberg - witten映射，我们研究了不同空间的规范对称性的等价问题，并对非对易空间的电磁场进行了微扰分析，最后我们对seiberg - witten映射的松动进行了讨论，研究发现这些松动中的一部分可以由规范变换吸收因而是可以忽略的，由于物质场的存在，另外一部分很难用规范变换和场的重定义吸收。 - The thesis deduces the generating functional of proper vertexes and brst transformation of the system of matter field coupling to non - abel gauge field , gives noether conservation charge of brst transformation , shows up the model ' s brst transformation when the gauges are lorentz , coulomb and radiation gauges , respectively , finishes the brst quantization of ghost field in ( 1 + 2 ) dimensions model with non - abel chern - simons term coupling to the scalar field , achieves the lagrange density and hamilton density under brst transformation
导出了物质场与非abel规范场耦合系统的brst变换以及此变换下的ward恒等式和正规顶角的生成泛函，给出了其brst变换下的noether守恒荷。针对lorentz规范、库伦规范、辐射规范三种情况分别给出了此模型的brst变换，并得到了自洽的结果。完成了( 1 + 2 )维时空中非abelchern - simon项和标量场耦合系统中鬼场的brst量子化，得到了brst变换下的noether荷和其对应的拉氏量和哈密顿量。
