Tyndall - by CrystalNerd18

Tyndall - an AI crafted indie song about Chiroptical Second-Harmonic Tyndall Scattering from Silicon Nanohelices. Experience the intersection of cutting-edge physics and experimental sound. This track explores the discovery of chiroptical second-harmonic Tyndall scattering (CHSTS)—a phenomenon where light is "doubled" and scattered by silicon (Si) nanohelices floating in the "medium of life": water. While traditional Tyndall scattering describes how light interacts with small particles, recent researches expand the regime into nonlinear optics. By illuminating silicon nanohelices with circularly polarized light, researchers observed a distinct chiroptical response that depends on the handedness of the light and the chirality of the nanoparticles. #AIart #AImusic #tech #science #Nanophotonics #Chirality #SiliconNanohelices #NonlinearOptics #Biomimetic #TyndallScattering 🔔 Like & subscribe for more releases.
