Simple theory of the inverse Faraday Effect with relationship to optical constants N and K
Journal of Magnetism and Magnetic Materials, 2011Co-Authors: Toshihiko YoshinoAbstract:The inverse Faraday Effect in general materials is theoretically investigated based on the classical motion of an electron. It is shown that the inverse Faraday Effect is simply and explicitly expressed in terms of optical constants N and K, i.e., the real and imaginary parts of complex refractive index of materials. The derived new formula provides a good physical perspective for the inverse Faraday Effect and enables its easy quantitative evaluation from familiar optical constants.

Theory for the Faraday Effect in optical fiber
Journal of the Optical Society of America B, 2005Co-Authors: Toshihiko YoshinoAbstract:The theoretical study of the fiber optic Faraday Effect based on the mode theory is conducted for the first time, to my knowledge. An analytical formula that represents the Faraday Effect in a single-mode fiber under the appropriate approximation is given as an explicit function of the refractive indices and Verdet constants of the core and cladding, the upsi-value of the fiber, the magnetic field, and the fiber length. The difference between the fiber optic and bulk-optic Faraday Effects is made clear. The Effect of the modal field spreading in the core and cladding on the fiber optic Faraday Effect is examined both analytically and numerically.

Faraday Effect of photonic crystals
Applied Physics Letters, 2003Co-Authors: C. Koerdt, Geert L. J. A. Rikken, E. P. PetrovAbstract:We measured Faraday rotation in three-dimensional photonic colloidal crystals impregnated with a Faraday active, transparent liquid. The Faraday Effect was found to strongly increase inside the stop band, whereas outside it follows the normal spectral behavior of a paramagnetic dielectric with an Effective Verdet constant equal to the product of the liquid’s Verdet constant and its filling fraction.

Nonexistence of the optical Faraday Effect
Optics Letters, 1995Co-Authors: Geert L. J. A. RikkenAbstract:It is experimentally shown that the optical Faraday Effect associated with a circularly polarized light beam and predicted by Evans [J. Mol. Liq. 55, 127 (1993)] does not exist.

Emulation of magneto-optic Faraday Effect using ultracold atoms.
New Journal of Physics, 2021Co-Authors: Zhen Zheng, Zhenghan WangAbstract:We propose an arresting scheme for emulating the famous Faraday Effect in ultracold atomic gases. Inspired by the similarities between the light field and bosonic atoms, we represent the light propagation in medium by the atomic transport in accompany of the laser-atom interaction. An artificial magneto-optic Faraday Effect is readily signaled by the spin imbalance of atoms, with the setup of laser fields offering a high controllability for quantum manipulation. The present scheme is really feasible and can be realized with existing experimental techniques of ultracold atoms. It generalizes the crucial concept of the magneto-optic Faraday Effect to ultracold atomic physics, and opens a new way of quantum emulating and exploring the magneto-optic Faraday Effect and associated intriguing physics.

Inverse Faraday Effect in graphene and Weyl semimetals
Physical Review B, 2020Co-Authors: I. D. Tokman, Qianfan Chen, I. A. Shereshevsky, V. I. Pozdnyakova, I. V. Oladyshkin, Mikhail Tokman, Alexey BelyaninAbstract:We report systematic theoretical studies of the inverse Faraday Effect in materials with massless Dirac fermions, both in two dimensions such as graphene and surface states in topological insulators, and in three dimensions such as Dirac and Weyl semimetals. Both semiclassical and quantum theories are presented, with dissipation and finite-size Effects included. We find that the magnitude of the Effect can be much stronger in Dirac materials as compared to conventional semiconductors. Analytic expressions for the optically induced magnetization in the low-temperature limit are obtained. Strong inverse Faraday Effect in Dirac materials can be used for the optical control of magnetization, all-optical modulation, and optical isolation.

Magneto-Optic Faraday Effect in Ultracold Atomic Gases
arXiv: Quantum Gases, 2020Co-Authors: Zhen Zheng, Z. D. WangAbstract:We propose an arresting scheme for simulating the famous Faraday Effect in ultracold atomic gases. Inspired by the similarities between the light field and the bosonic atoms, we represent the light propagation in medium by the atomic transport in accompany of the laser-atom interaction. The artificial magneto-optic Faraday Effect is readily signaled by the spin imbalance of atoms, with the setup of laser fields offering a high controllability for quantum manipulation. Our proposal can be realized with current experimental techniques of ultracold atoms, and is quite promising for exploring and investigating the magneto-optic Faraday Effect and associated physics.
