Raman optical activity, long thought to require chiral molecules or magnetic order, has been demonstrated in an achiral, ...

Weyl semimetals, a class of quantum materials defined by their unique band structure, host emergent chiral Weyl fermions that exhibit distinct physical properties. These materials hold great potential ...

Scientists at the University of Oxford demonstrate an approach to interpreting how materials interact with polarized light, which could help advance biomedical imaging and material design. Subscribe ...

Almost a decade ago, Harvard engineers unveiled the world's first visible-spectrum metasurfaces—ultra-thin, flat devices patterned with nanoscale structures that could precisely control the behavior ...

Schematic illustration of chiral plasmonic nanorods (HPNR@SiO₂) converting CO₂ to CH₄ under circularly polarized light. The matched chirality of light and catalyst enhances hot-electron generation and ...

A new LED design uses a built-in nanoscale metasurface to emit circularly polarized light directly, eliminating bulky optics for 3D displays and AR devices. (Nanowerk News) From 3D movie screens to ...

Researchers have created a bilayer metasurface made of two stacked layers of titanium dioxide nanostructures, opening new possibilities for structuring light. Almost a decade ago, Harvard engineers ...
