Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a chip-scale device ...

In recent years, van der Waals crystals have evolved from scientific curiosities into a versatile platform for exploring novel quantum phases and unconventional nanophotonic phenomena. Their layered ...

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

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 ...

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 ...
