A. Shariati, M. Khorrami, A. H. Fatollahi

摘要:

给出了空间坐标系间具有线性Lie型非对易性的空间的旋量理论。该模型基于与空间坐标相对应的傅立叶空间,因为该傅立叶空间是可交换的。当群是紧的时,实空间表现出格特征(因为空间算子的本征值是离散的),并且这种\emph{lattice}与普通格的相似性在类似于著名的\emph{fermion doubling}问题的现象中表现出来。引入投影使旋量的动力学数等于对应于普通空间的旋量数。自由和相互作用的旋量(费米类相互作用)的行动。Feynman规则的提取和单回路校正进行了研究。

英文摘要:

A spinor theory on a space with linear Lie type noncommutativity among spatial coordinates is presented. The model is based on the Fourier space corresponding to spatial coordinates, as this Fourier space is commutative. When the group is compact, the real space exhibits lattice characteristics (as the eigenvalues of space operators are discrete), and the similarity of such a \emph{lattice} with ordinary lattices is manifested, among other things, in a phenomenon resembling the famous \emph{fermion doubling} problem. A projection is introduced to make the dynamical number of spinors equal to that corresponding to the ordinary space. The actions for free and interacting spinors (with Fermi-like interactions) are presented. The Feynman rules are extracted and 1-loop corrections are investigated.
