非中心对称金属中的无色散旋光

Dispersion-free optical activity in non-centrosymmetric metals

V. P. Mineev

备注：
6 pages, no figures. arXiv admin note: text overlap with arXiv:1903.04400 The statement about nonzero antisymmetric tensor of conductivity in noncentrosymmetric metals with point group $C_{4v}$ is wrong. The error was made in the Eq.(24) for v_{\pm}. As result, in Eq.(36) σ^a{xy}=0. The corresponding optical properties do not take place

摘要：

根据昂萨格原理，在不违反时间反演对称性的系统中，动力学系数矩阵是对称的。反对称性在时间反演对称性破缺的系统中是可能的。在外部磁场中的系统中。这里介绍这一规则的一个例外。结果表明，在点群为$C_{4v}$且不违反时间反演的四元金属中，电导率张量是反对称的。相应的光学性质被认为是。

英文摘要：

According to the Onsager principle a matrix of kinetic coefficients is symmetric in a system not violating time inversion symmetry. The antisymmetry is possible in systems with broken time inversion symmetry f.i. in systems in external magnetic field. An exception to this rule is presented here. It is shown that in a tetragonal metals with point group $C_{4v}$ not violating time inversion the conductivity tensor is antisymmetric. The corresponding optical properties are considered.
