论文摘要
本文涉及与面向外部磁场和电场的石墨烯型材料的低能界面dirac模型相关的不对称传输。我们表明，相关的物理可观察到的界面电导率是对大量扰动的量化且健壮的。这些包括沿着接口或远离接口的缺陷，以及外部场中足够的小或局部变化。界面电导率的明确公式由光谱流给出。
This paper concerns the asymmetric transport associated with a low-energy interface Dirac model of graphene-type materials subject to external magnetic and electric fields. We show that the relevant physical observable, an interface conductivity, is quantized and robust to a large class of perturbations. These include defects that decay along or away from the interface, and sufficiently small or localized changes in the external fields. An explicit formula for the interface conductivity is given by a spectral flow.
