“…Therefore they contribute to different effects and can be distinguished by a proper choice of experimental geometry. MSD has been demonstrated in reflection and transmission experiments on various bulk semiconductors: GaAs [5], CdSe [6], ZnTe, CdTe [7], CdZnTe [8], thin films [9], magnetic semiconductors [10], as well as in the second optical harmonics generation in ZnO [11]. Here we report on the observation of MSD in quantum well structures.…”

“…Here q α and B β are components of the light wavevector q and the magnetic field B [22,23], (see also [24] and references therein). In chiral CNs the magneto-chiral dichroism can be described by the following contribution to the absorption or emission probability rate [24]…”

We consider chirality related effects in optical, photogalvanic and electron-transport properties of carbon nanotubes. We show that these properties of chiral nanotubes are determined by terms in the electron effective Hamiltonian describing the coupling between the electron wavevector along the tube principal axis and the orbital momentum around the tube circumference. We develop a theory of photogalvanic effects and a theory of d.c. electric current, which is linear in the magnetic field and quadratic in the bias voltage. Moreover, we present analytic estimations for the natural circular dichroism and magneto-spatial effect in the light absorption.Comment: 23 pages, 3 figure

“…In the transparency region it manifests as non-reciprocal birefringence, studied in several semiconductors such as wurtzite CdSe, 8 and cubic GaAs, CdTe and ZnTe. 9,10 Nonreciprocal birefringence was also demonstrated in the diluted magnetic semiconductor (Cd,Mn)Te.…”

We study the polarization dynamics of exciton-polaritons propagating in sub-mm thick (Cd,Zn)Te bulk crystals using polarimetric time-of-flight techniques. The application of a magnetic field in Faraday geometry leads to synchronous temporal oscillations of all Stokes parameters of an initially linearly or circularly polarized, spectrally broad optical pulse of 150 fs duration propagating through the crystal. Strong dispersion for photon energies close to the exciton resonance leads to stretching of the optical pulse to a duration of 200−300 ps and enhancement of magneto-optical effects such as the Faraday rotation and the non-reciprocal birefringence. The oscillation frequency of the excitonpolariton polarization increases with magnetic field B, reaching 10 GHz at B ∼ 5 T. Surprisingly, the relative contributions of Faraday rotation and non-reciprocal birefringence undergo strong changes with photon energy, which is attributed to a non-trivial spectral dependence of Faraday rotation in the vicinity of the exciton resonance. This leads to polarization nutation of the transmitted optical pulse in the time domain. The results are well explained by a model that accounts for Faraday rotation and magneto-spatial dispersion in zinc-blende crystals. We evaluate the exciton g-factor |gexc| = 0.2 and the magneto-spatial constant V = 5 × 10 −12 eVcmT −1 .
