石墨烯中的宇称奇效应和极化旋转

Parity-odd effects and polarization rotation in graphene

I. V. Fialkovsky, D. V. Vassilevich

摘要:

我们表明,奇偶奇项的存在下的电导率(或者,换句话说,在极化张量的狄拉克准粒子在石墨烯)导致旋转的极化的电磁波通过悬浮样品的石墨烯。奇宇称陈-西蒙斯型贡献出现在外部磁场中,引起量子法拉第效应(尽管也可以讨论奇宇称效应的其他来源)。这种效应的估计量级远高于现代光学仪器的灵敏度极限。

英文摘要:

We show that the presence of parity-odd terms in the conductivity (or, in other words, in the polarization tensor of Dirac quasiparticles in graphene) leads to rotation of polarization of the electromagnetic waves passing through suspended samples of graphene. Parity-odd Chern-Simons type contributions appear in external magnetic field, giving rise to a quantum Faraday effect (though other sources of parity-odd effects may also be discussed). The estimated order of the effect is well above the sensitivity limits of modern optical instruments.
