feV
- (Métrologie, Physique) (Extrêmement rare) Symbole du femtoélectronvolt, unité de mesure d’énergie en dehors du Système international (mais dont l’usage est accepté avec le SI), valant 10−15 électronvolt.
- When the photons involved are very tiny, as they are in decahertz waves, with energies in the femtoelectronvolt range, there are so many of them in structures as big as brainwaves that classical wave analysis can take us a long way, but strictly speaking we’re dealing with a quantum reality here. […] There are three obvious differences:
• Brainwave photons have much lower energies, on the order of 100 feV, so the time evolution of phenomena such as decoherence is trillions of times slower than that of visible-light laser beams. — (J. Andrew Ross, Mindworlds: A Decade of Consciousness Studies, Imprint Academic, Exeter (GB), 2015, ISBN 978-1-84540-185-6)
