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 ...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a chip-scale device that can dynamically control the "handedness" of light as it passes ...

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 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 ...

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 ...

A team of chemists has made significant strides in the field of mechanically interlocked molecules (MIMs). Their work showcases the development of a compact catenane with tuneable mechanical chirality ...
