Synthesis of hybrid gold-protein nanobioconjugates with strongly enhanced circular dichroism
Yoann Prado, Victoire Ho, Maud Virolle +7
The study creates hybrid gold‑protein nanoconjugates that generate superchiral near fields, leading to a roughly three‑fold increase in the circular dichroism signal of photosynthe…
Light-Driven Skyrmion Crystal Generation in Plasmonic Metasurfaces Through the Inverse Faraday Effect
Xingyu Yang, Chantal Hareau, Tristan da Câmara Santa Clara Gomes +2
Skyrmions are topological structures defined by a winding vector configuration that yields a quantized topological charge. In magnetic materials, skyrmions manifest as stable, mobi…
All-optical directional switching of non-thermal photocurrents in plasmonic nanocircuits
Roméo Zapata, Diana Singh, Obren Markovic +9
Controlling the flow of electricity in metallic circuits with light is a key goal for future optoelectronics. In this work, we demonstrate all-optical generation and directional co…
Engineering Magnetization with Photons: Nanoscale Advances in the Inverse Faraday Effect for Metallic and Plasmonic Systems
Chantal Hareau, Xingyu Yang, Maria Sanz +2
The inverse Faraday effect, the ability of light to act as a source of magnetism, is a cornerstone of modern ultrafast optics. Harnessing this effect at the nanoscale promises to t…
Twisting Light, Steering Spins: Gold Nanoparticle Magnetization via Inverse Faraday and Orbital Angular Momentum
Xingyu Yang, Chantal Harreau, Mathieu Mivelle
We present a new approach to controlling magnetization in gold nanoparticles using the Inverse Faraday Effect combined with Laguerre-Gauss beams carrying orbital angular momentum.…
