Quantum Optomagnetics in Graphene
arXiv:2207.04563 · doi:10.1088/1361-6455/ace395
Abstract
Graphene can be magnetized through nonlinear response of its orbital angular momentum to an intense circularly polarized light. This optomagnetic effect can be well exemplified by the Inverse Faraday Effect (IFE) where an optically-generated DC magnetization leads to graphene's optical activity. We provide a single-particle quantum mechanical model of an IFE in graphene by solving Schrödinger's equation in the presence of a renormalized Hamiltonian near a Dirac point in the presence of circularly polarized monochromatic light. We derive an analytical expression for DC magnetization based on non-perturbative and dressed states of quasi-electrons where their energy spectrum is isotropically gapped by the circularly polarized light. Optical rotatory power is then computed through the gyroelectric birefringence where a measurable polarization rotation angle under moderate and intense optical radiations is predicted.
