Although proposed theoretically over a decade ago, experimental demonstrations have remained elusive. Here we report the observation of spin-mechanical coupling in a carbon nanotube device. We demonstrate this coupling in two configurations: off-resonant, with spin and mechanics excited by separate tones, and resonant, driven by a single tone. The coupling manifests as a shift and broadening of the electric dipole spin resonance (EDSR), respectively. Our theoretical model, which accounts for the tensor character of the coupling and mechanical non-linearity, reproduces the data with very good agreement. Our results demonstrate a previously unobserved spin-mechanical coupling, offering versatile tools for exploring macroscopic quantum phenomena, quantum thermodynamics, and quantum simulation.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Coupling a single spin to the motion of a carbon nanotubejournal article2041-1723https://dx.doi.org/10.1038/s41467-025-66331-5https://www.nature.com/articles/s41467-025-66331-5open access53Mechanical ResonatorCoherentFísica (Física)22 Física
