TL;DR: Enhanced third-harmonic generation from silicon nanodisks exhibiting both electric and magnetic dipolar resonances is observed and the field localization at the magnetic resonance results in two orders of magnitude enhancement of the harmonic intensity with respect to unstructured bulk silicon.

TL;DR: This work implements a new physical mechanism for suppressing radiative losses of individual nanoscale resonators to engineer special modes with high quality factors: optical bound states in the continuum (BICs), and demonstrates that an individual subwavelength dielectric resonator hosting a BIC mode can boost nonlinear effects increasing second-harmonic generation efficiency.

TL;DR: It is demonstrated that the hysteresis-type dependence of the magnetic permeability on the field intensity allows changing the material properties from left- to right-handed and back.

TL;DR: An overview of the dynamics of one of the fundamental models of low-dimensional nonlinear physics, the Frenkel-Kontorova (FK) model, is presented in this article.

TL;DR: Control of light at the nanoscale is demanding for future successful on-chip integration and most optical nanoantennas consist of plasmonic nanoparticles due to their ability to capture and concentrate visible light at subwavelength dimensions.
