Topological kink plasmons on magnetic-domain boundaries

Topological kink plasmons on magnetic-domain boundaries

Topological kink modes are peculiar edge excitations that take place at domain boundaries of magnetic fields inside homogeneous materials. Here, the authors experimentally observe kink magnetoplasmons in a 2D electron gas using custom-shaped strong permanent magnets on top of a GaAs/AlGaAs heterojun...
