Quantized topological magnetoelectric effect of the zero-plateau quantum anomalous Hall state
Quantized topological magnetoelectric effect of the zero-plateau quantum anomalous Hall state
Topological magnetoelectric effect in a three-dimensional topological insulator is a novel phenomenon, where an electric field induces a magnetic field in the same direction, with a universal coefficient of proportionality quantized in units of $e^2/2h$. Here we propose that the topological magnetoelectric effect can be realized in the zero-plateau quantum …
