    Two-dimensional (2D) materials, despite their small thickness, can display chirality that enables prominent asymmetric optical, electrical transport, and magnetic properties. This Perspective discusses the intriguing physics enabled by the structural chirality and the possible ways to create and control chirality in 2D materials.

    Inspired by valley pseudospins in two-dimensional materials, high-quality-factor (high-Q) spin–valley states were created through the photonic Rashba-type spin splitting of a bound state in the continuum. This approach enabled the construction of a coherent and controllable spin-optical laser using monolayer-integrated spin–valley microcavities without requiring magnetic fields or cryogenic temperatures.

    The authors introduce a spin-optical laser based on a monolayer transition metal dichalcogenide coupled to a heterostructure microcavity supporting high-Q spin-valley resonances originating from photonic Rashba-type spin splitting of a bound state in the continuum.

    A scalar scheme has been proposed to design photonic crystals that possess bulk dispersions resembling scalar waves and surface modes that support skyrmion-like textures. This approach addresses the challenges of realizing three-dimensional topological photonic crystals, which usually have complicated dispersions and leaky surface modes inside the light cone.

    Colloidal nanocrystals can form into periodic superlattices exhibiting collective vibrations from the correlated motion of the nanocrystals. This Perspective discusses such collective vibrations and their as-of-yet untapped potential applications for phononic crystals, acoustic metamaterials and optomechanical systems.
