Researchers observe how a photoinduced hidden state forms within 30 femtoseconds

Researchers at NC State have extended twistronics beyond van der Waals materials into strongly bonded crystalline oxides. By stacking sodium niobate membranes with twist angles controlled down to 0.1 degrees, and confirming results via synchrotron X-ray diffraction, the team found interlayer bonds distort the atomic lattice, shifting phase structure and domain configuration. The technique works at near-millimeter scale, far larger than typical twistronic devices, marking a re

When fast-moving electrons pass over nanostructured materials, they can make those materials emit light — a phenomenon called cathodoluminescence, already widely used in electron microscopy. The catch has always been controlling where that light goes once it's generated. Researchers from the University of Southern Denmark, with collaborators at ICFO and AMOLF, have now proposed a theoretical fix: programmable metasurfaces built from individually tunable nanoscale elements, us

Scientists at the Max Planck Institute for the Science of Light (MPL) have developed a technique for interrogating molecules on surfaces with spectroscopic precision and thereby reaching the ultimate quantum limit for the first time. With their findings, published in Science, the researchers open new opportunities for the study of molecule-surface interactions and molecular quantum technologies.

Researchers at the University of Technology Sydney (UTS), in collaboration with the University of Minnesota and Kyung Hee University, have discovered a powerful new way to control tiny quantum light sources by twisting atomically thin layers of hexagonal boron nitride (hBN). In a study published in Science Advances, the team demonstrated that by stacking and twisting hBN layers, they could significantly shift the color and wavelength of quantum emitters. This twistable platfo

Researchers at Carnegie Mellon University, in collaboration with Stanford and Purdue, have demonstrated a powerful new way to control heat at the nanoscale. Using carefully engineered metamaterials — microscopic gold patterns on thin membranes — they achieved up to four times more heat transfer across a tiny gap compared to conventional setups.
