论文摘要
光磁学成为研究的越来越多的研究交联光学，磁性和材料科学领域。在这里，我们提供了微观量子机械和宏观经典模型，以描述非线性光学观点的光磁效应。我们的自洽量子机械配方考虑了扰动场的所有顺序和结果，不仅在找到普遍的Pitaevskii关系中，可以通过光功率扩展光诱导的磁化强度，还为光学和分析表达式提供了光学和分析表达式。然后，基于Anharmonic Drude-Lorentz模型开发经典处理，表明光诱导的DC磁化与光功率的奇数谐波成正比。揭示和讨论了量子和经典结果的差异。考虑到易探针的设置，我们描述了探针信号如何通过其介电常数张量并找到光传播特性来传播光磁介质，即通过强烈圆形的泵光磁化的培养基。由于圆形和线性双折射及其Verdet常数，讨论了反向法拉第和棉花摩托顿效应。
Optomagnetics emerges as a growing field of research cross-linking optics, magnetism and material science. Here, we provide a microscopic quantum mechanical and a macroscopic classical models to describe optomagnetic effects from nonlinear optics point of view. Our self-consistent quantum mechanical formulation considers all orders of perturbing field and results not only in finding generalized Pitaevskii's relationship, where photoinduced magnetization can be expanded in terms of light power, but also provide compact and analytical expressions for optical gyration vector coefficients. classical treatment is then developed based on the anharmonic Drude-Lorentz model showing that the photo-induced DC magnetization is proportional to odd harmonics of the light power. The difference in quantum and classical results are revealed and discussed. Having a pomp-probe setup in mind, we describe how a probe light signal can propagate down an optomagnetic medium, i.e. a medium that is magnetized by intense circularly-polarized pump light, via its permittivity tensor and find light propagation characteristics. Inverse Faraday and Cotton-Mouton Effects are discussed as a result of circular and linear birefringences and their Verdet constants have been analytically found.
