Zero-Point Energy
The lowest energy that a quantum system retains at absolute zero. It is nonzero, rooted in the Heisenberg uncertainty principle; the zero-point energy of a simple harmonic oscillator is ½ℏω.

Zero-point energy is the lowest energy a quantum system still possesses at absolute zero, rooted in Heisenberg's uncertainty principle; the zero-point energy of a simple harmonic oscillator is ½ℏω, and the ground-state energy of the hydrogen atom is -13.6 eV.
Phenomena such as the Casimir effect and the fact that liquid helium does not solidify at ordinary pressure are related to zero-point energy.
