Electron-induced nonlinear dynamics in atomic chains
We study the nonlinear response of collective optical resonances in linear atomic chains with metallic, semiconducting, and topologically insulating character to low-energy free electrons. The nonlinearity, which manifests in the amplitude and frequency of resonant features in cathodoluminescence an...
