Robust Edge States from Band Topology in a Damped One-dimensional Magnonic Crystal
Kwangyul Hu, Denis R. Candido, Michael E. Flatté
The presence or absence of topologically-produced edge states of a crystal are robust to disorder; their stability in the presence of decay is less clear. For topologically nontriv…
