论文摘要
我们报告了无质量的dirac费米斯材料中反向法拉第效应的系统理论研究，无论是在拓扑绝缘子中的石墨烯和表面状态等两个维度，以及在三个维度（例如dirac和weyl semimimetals）中。出现了半古老和量子理论，包括耗散和有限的尺寸效应。我们发现，与常规半导体相比，狄拉克材料的效果的大小可能更强。获得了低温极限中光学诱导磁化的分析表达式。狄拉克材料中强的反向法拉第效应可用于磁化，全光调制和光学隔离的光学控制。
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.
