一个拓扑异常目前在零能量示出引起一个特殊的和奇异的行为的动态和静态的电导率在二维蜂窝晶格。在自洽玻恩近似的计算表明，这种奇异的依赖占主导地位，虽然有点平滑，即使考虑到水平加宽效应。
A topological anomaly present at zero energy is shown to give rise to a peculiar and singular behavior of the dynamic and static conductivity in two-dimensional honeycomb lattices. A calculation in a self-consistent Born approximation reveals that this singular dependence prevails although being somewhat smoothed out even if level broadening effects are taken into account.
