石墨烯中的量子场论
Quantum Field Theory in Graphene
摘要:
这是一个简短的非技术性的介绍应用的量子场论方法石墨烯。我们从紧束缚模型导出狄拉克模型,并描述极化算子(电导率)的计算。随后,我们用这个量来描述量子霍尔效应、石墨烯的光吸收、法拉第效应和卡西米尔相互作用。
英文摘要:
This is a short non-technical introduction to applications of the Quantum Field Theory methods to graphene. We derive the Dirac model from the tight binding model and describe calculations of the polarization operator (conductivity). Later on, we use this quantity to describe the Quantum Hall Effect, light absorption by graphene, the Faraday effect, and the Casimir interaction.
