Dispersion-free optical activity in non-centrosymmetric metals
Abstract
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 not violating time inversion the conductivity tensor is antisymmetric. The corresponding optical properties are considered.

Comments
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) \sigma^a{xy}=0. The corresponding optical properties do not take place
