Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked ...

Chirality is an essential property in biology; the molecular building blocks of some of the most important biological structures, including DNA and proteins, are chiral. When a molecule is said to be ...

Engineers created a MEMS-tunable twisted bilayer photonic crystal chip that dynamically adjusts twist angle and spacing to ...

Artistic representation of hyper-Raman optical activity: twisted light (red helices) incident on molecules arranged on a helical scaffold (white dots) produce hyper-Raman scattering spectra ...

(a) Electric field of LCP and superchiral light. (b) (Left) Schematic illustrating the generation of superchiral fields by focusing twisted RP beams. (Right) Theoretical model used to calculate the ...

Chirality is a fundamental property of asymmetry in nature, where an object or molecule cannot be superimposed onto its mirror image. In the context of nanotechnology, chirality refers to the ...
