Quantum vibration; QHO; Quantum mechanical harmonic oscillator; Quadratic potential; Harmonic potential; Quantum oscillator; Harmonic oscillator (quantum); Quantum-mechanical harmonic oscillator; Time-dependent quantum harmonic oscillator with an applied linear electric field; Linear harmonic oscillator; Quantum harmonic oscillators
The quantum harmonic oscillator is the quantum-mechanical analog of the classical harmonic oscillator. Because an arbitrary smooth potential can usually be approximated as a harmonic potential at the vicinity of a stable equilibrium point, it is one of the most important model systems in quantum mechanics.
