The potential energy of a harmonic oscillator
WebbAt 59:14 in this video, the expectation value of the energy of a harmonic oscillator is (1) E = ∫ Ψ ~ ( p) 2 p 2 2 m d p + ∫ Ψ ( x) 2 m ω 2 2 x 2 d x My question is how was this … WebbThus, if the thermal energy is much less than the spacing between quantum states then the mean energy approaches that of the ground-state (the so-called zero point energy). Clearly, the equipartition theorem is only valid in the former limit, where , and the oscillator possess sufficient thermal energy to explore many of its possible quantum states.
