Zero-point energy

{
  "id": "MLC-T-CHM-012805",
  "term": "Zero-point energy",
  "field": "Chemistry",
  "definition": "The minimum possible energy that a quantum mechanical system can possess, even at absolute zero temperature. This energy arises from the inherent uncertainty in position and momentum, as described by the Heisenberg uncertainty principle, preventing particles from being perfectly stationary. For a harmonic oscillator, the zero-point energy is given by 1/2hν, where h is Planck's constant and ν is the vibrational frequency.",
