zero point energy
Définition
- Zero-point energy (ZPE) is the kinetic energ, which, in accordance with the uncertainty principle, is retained by a substance at absolute zero (each component oscillator retaining one half quantum (hν/2) energy). Alternatively, the energy left behind in a volume of space after all the matter and radiation has been removed. Zero-point energy (ZPE), also known as vacuum fluctuation energy, is predicted by quantum mechanics and gives rise to some measurable phenomena such as the Lamb shift and the Casimir effect.
