摘　　要：“Axion”was predicted as a hypothetical elementary particle to resolve the strong conjugation-parity problem in particle physics,^([1])and it is also an attractive candidate for the as-yet-unobserved dark matter in cosmology.^([2])While the detection of axions still remains elusive in particle physics and cosmology,it was recently proposed that the elegant physics of axions,known“axion electrodynamics”,^([3])can emerge in certain condensed matter systems,particularly topological insulator materials,^([4])in which a variety of exotic physical phenomena(e.g.topological magnetoelectric effect)have been theoretically predicted.
