TL;DR: In this paper, the authors discuss the recent advances in meta-optics and nanophotonics associated with the physics of bound states in the continuum (BICs), and propose novel applications of the BIC physics to all-dielectric optical metasurfaces with broken-symmetry meta-atoms when tuning to BIC conditions allows to enhance substantially the $Q$ factor of the flatoptics dielectric structures.

TL;DR: In this article, nonlinear properties of a multi-layer stack of graphene sheets are studied and the existence of single and multi-hump dissipative solitons in the graphene structure is predicted.

TL;DR: In this article, the spin angular momentum density of hybrid surface waves propagating along anisotropic hyperbolic metasurfaces was analyzed and it was shown that the spin of the hybrid surface wave can be engineered to have an arbitrary angle with the propagation direction.

TL;DR: It is shown how to generate robust self-sustained clusters of soliton bullets-spatiotemporal (optical or matter-wave) solitons that carry an orbital angular momentum being supported by competing nonlinearities.

Abstract: We demonstrate both experimentally and numerically multifold enhancement of magneto-optical effects in subwavelength dielectric nanostructures with a magnetic surrounding exhibiting localized magnetic Mie resonances. We employ amorphous silicon nanodisks covered with a thin nickel film and achieve the 5-fold enhancement of the magneto-optical response of the hybrid magnetophotonic array of nanodisks in comparison with a thin nickel film deposited on a flat silica substrate. Our findings allow for a new basis for active and nonreciprocal photonic nanostructures and metadevices, which could be tuned by an external magnetic field.
