The lowest possible energy of a given quantum mechanical system.
Definition source: English Wiktionary via Wiktextract
Qualifier: quantum mechanics
Topics: natural-sciences, physical-sciences, physics
Examples
- The existence of a zero-point energy (i.e., the existence of a non-zero lower limit to the energy of a quantum-mechanical system) is a consequence of Heisenberg's uncertainty principle.
- 2000, Stephen T. Thornton, Andrew F. Rex, Modern Physics for Scientists and Engineers, Saunders College Publishing, page 205, Our estimate for the zero-point energy of the harmonic oscillator is hbar ω/2.
