“…This effect, named magnetochiral dichroism, is due to the interplay between the linear perturbation of the magnetic field and the radiation induced polarization of chiral molecules, which leads enantiomers to absorb differently a light traveling parallel or antiparallel to an applied magnetic field (Barron and Vrbancich, 1984;Wagnière, 1999). As for CPL, magnetochiral anisotropy has its basis in the difference in absorption coefficients between enantiomers of a chiral species and depends on both the resulting factor g and the strength of the magnetic field B in the form: g B.…”

We present a comprehensive study of various electromagnetic wave propagation phenomena in a ferromagnetic bulk Rashba conductor from the perspective of quantum mechanical transport. In this system, both the space inversion and time reversal symmetries are broken, as characterized by the Rashba field α and magnetization M , respectively. First, we present a general phenomenological analysis of electromagnetic wave propagation in media with broken space inversion and time reversal symmetries based on the dielectric tensor. The dependence of the dielectric tensor on the wave vector q and M are retained to first order. Then, we calculate the microscopic electromagnetic response of the current and spin of conduction electrons subjected to α and M , based on linear response theory and the Green's function method; the results are used to study the system optical properties. Firstly, it is found that a large α enhances the anisotropic properties of the system and enlarges the frequency range in which the electromagnetic waves have hyperbolic dispersion surfaces and exhibit unusual propagations known as negative refraction and backward waves. Secondly, we consider the electromagnetic cross-correlation effects (direct and inverse Edelstein effects) on the wave propagation. These effects stem from the lack of space inversion symmetry and yield q-linear off-diagonal components in the dielectric tensor. This induces a Rashba-induced birefringence, in which the polarization vector rotates around the vector (α × q). In the presence of M , which breaks time reversal symmetry, there arises an anomalous Hall effect and the dielectric tensor acquires off-diagonal components linear in M . For α M , these components yield the Faraday effect for the Faraday configuration q M , and the Cotton-Mouton effect for the Voigt configuration (q ⊥ M ). When α and M are noncollinear, M -and q-induced optical phenomena are possible, which include nonreciprocal directional dichroism in the Voigt configuration. In these nonreciprocal optical phenomena, a "toroidal moment," α × M , and a "quadrupole moment," αiMj + αjMi, play central roles. These phenomena are strongly enhanced at the spin-split transition edge in the electron band.

“…Magneto-chiral dichroism (MChD) [1][2][3][4][5][6][7][8][9][10] is related to the difference in the absorption coefficients of a chiral molecule in a magnetic field parallel and antiparallel to the incident light beam. In other words, if one shines light (in any polarization state) on a chiral species in presence of a static magnetic field with a component parallel to the direction of propagation of the light, the absorption coefficient n ↑↑ for B (magnetic field) and k (direction of propagation) parallel to each other differs from the one measured for B and k antiparallel, n ↑↓ .…”

“…The same occurs for the refractive indices, and the resulting birefringence, corresponding to an anisotropy of the phase of the beams, is then known as magneto-chiral birefringence (MChB).

A computational protocol for magneto-chiral dichroism and magneto-chiral birefringence dispersion is presented within the framework of damped response theory, also known as complex polarization propagator theory, at the level of time-dependent Hartree-Fock and time-dependent density functional theory. Magneto-chiral dichroism and magneto-chiral birefringence spectra in the (resonant) frequency region below the first ionization threshold of R-methyloxirane and l-alanine are presented and compared with the corresponding results obtained for both the electronic circular dichroism and the magnetic circular dichroism. The additional information content yielded by the magneto-chiral phenomena, as well as their potential experimental detectability for the selected species, is discussed.
