Carbon Nanotubes Proposed for Light Dark Matter Detection

Researchers have put forth a theoretical concept suggesting the use of metallic carbon nanotubes as a new type of detector for light dark matter. This innovative approach would utilize the collective Luttinger-liquid mode in CNTs, differing from traditional electron-hole pair excitation methods. The proposal outlines potential sensitivities for dark matter-electron scattering, potentially opening new avenues for detecting sub-MeV dark matter, though these are preliminary theoretical findings.
