The 22 pages that link to Ground state, each with the reason it gives.

• Electron configurationRelated: The usual configuration describes the ground state, not every possible occupation.

• Quantum harmonic oscillatorBroader topic: The oscillator ground state retains energy even when no excitations are present.

• Bose–Einstein condensateRelated: The condensate is defined by macroscopic occupation of this state.

• Internal energyRelated: Quantum systems can retain nonzero ground-state energy even at absolute zero.

• Energy levelRelated: It is the bottom level from which excitation energy is measured.

• Absolute zeroRelated: At absolute zero, an equilibrium system occupies its ground state.

• Fermi energyRelated: The Fermi energy is defined by occupation in the fermionic ground state.

• Zero-point energyRelated: Zero-point energy is the energy the system retains in this state.

• Excited stateCompared with: It is the reference state whose energy an excited state exceeds.

• Atomic energy levelRelated: It is the atom’s most stable energy level under specified conditions.

• PhosphorescenceRelated: Phosphorescence ends when the excited system returns to this state.

• Hund's rulesNarrower topic: Hund's rules identify the ground term within a configuration, not the ground state across all configurations.

• Third law of thermodynamicsRelated: A unique ground state supports the zero-entropy limit for a perfect crystal.

• Topological orderRelated: Topological systems can have multiple ground states that remain indistinguishable by local measurements.

• Direct method in the calculus of variationsRelated: Variational methods often seek ground states by minimizing an energy functional.

• Lyman seriesRelated: The fixed destination of every transition in the Lyman series.

• Rydberg atomCompared with: Unlike a Rydberg state, an atom's ground state has a compact electron distribution.

• LuminescenceRelated: Emission commonly returns an excited system toward this lower-energy state.

• Hund's rule of maximum multiplicityRelated: Hund's rule helps predict ground-state electron arrangements in partially filled subshells.

• Principle of minimum energyBroader topic: It is the quantum-mechanical case of selecting the lowest accessible energy.

• QED vacuumRelated: The QED vacuum is a ground state, rather than a region with literally nothing in it.

• Quantum vacuum stateNarrower topic: A quantum vacuum is the ground state of a field, not necessarily an empty space.
