4 dni temu · Zero-point energy ( ZPE) is the lowest possible energy that a quantum mechanical system may have. Unlike in classical mechanics, quantum systems constantly fluctuate in their lowest energy state as described by the Heisenberg uncertainty principle. [1] . Therefore, even at absolute zero, atoms and molecules retain some vibrational motion.
