Advancing photonics materials with cellular automation

Dec 15, 2021 (Nanowerk News) Researchers from the Singapore University of Technology and Design (SUTD) have designed a novel computational model that accurately predicts the properties of photonics materials, paving the way for next-generation photonics devices. Their findings, published in npj Computational Materials ("A scheme for simulating multi-level phase change...

Physicists see an unusual quantum phenomenon

Dec 14, 2021 (Nanowerk News) A highly unusual movement of light emitting particles in atomically-thin semiconductors was experimentally confirmed by scientists from the Würzburg–Dresden Cluster of Excellence ct.qmat–Complexity and Topology in Quantum Matter. Electronic quasiparticles, known as excitons, seemed to move in opposite directions at the same time. Professor Alexey...

Color-sorting metalenses boost imaging sensitivity

Dec 14, 2021 (Nanowerk News) Researchers have shown that newly designed pixel-scale metasurface lenses — flat surfaces that use nanostructures to manipulate light — can be used to make imaging sensors that are roughly three times more sensitive than those used today. The new sensor architecture could enable digital cameras...

Losing isn’t always bad: Gaining topology from loss

Dec 14, 2021 (Nanowerk News) Losing particles can lead to positive, robust effects. An international collaboration has demonstrated a novel topology arising from losses in hybrid light-matter particles, introducing a new avenue to induce the highly-prized effects inherent to conventional topological materials, which can potentially revolutionise electronics. Led by Singapore’s...

Surfing the spin wave in graphene

Dec 14, 2021 (Nanowerk News) Spin waves, a change in electron spin that propagates through a material, could fundamentally change how devices store and carry information. These waves, also known as magnons, don’t scatter or couple with other particles. Under the right conditions, they can even act like a superfluid,...
