Web. Web. In particular, n = 0 means that the harmonic oscillator will stay at its ground state. Usually, the ground state of a quantum system is assumed to be lived at zero temperature. Therefore, you can find a connection between n = 0 and zero-point. Here is a post to talk about the relationship between zero temperature and ground state. Web. Web.

This leads to the concept of zero-point energy. Zero-point energy is the energy that remains when all other energy is removed from a system. This behaviour is demonstrated by, for example, liquid helium. As the temperature is lowered to absolute zero, helium remains a liquid, rather than freezing to a solid, owing to the irremovable zero-point .... Web. Web.

Second, these discrete energy levels are equally spaced, unlike in the Bohr model of the atom, or the particle in a box. Third, the lowest achievable energy (the energy of the n = 0 state, called the ground state) is not equal to the minimum of the potential well, but ħω/2 above it; this is called zero-point energy. Sep 15, 2008 · In a recent thermodynamic analysis of the harmonic oscillator Boyer has shown, using an interpolation procedure, that the existence of a zero-point energy leads to Planck’s law.

Make the (handwaving, but usual) assumption that the momentum must be greater than the uncertainty in momentum, and that the position must be greater than the uncertainty in position. Start by writing the total energy (KE + PE) in terms of those uncertainties. Minimize that to find the lowest allowable energy.. Short answer: By the uncertainty principle, the harmonic oscillator can't be localized at the minimum value of potential energy, i.e., x = 0, because, by the uncertainty principle, it's momentum would become large (strictly speaking, the expectation value of p 2, and thereby it's kinetic energy, becomes large).

Web. In a paper, I ran into the following definition of the zero point fluctuation of our favorite toy, the harmonic oscillator: x Z P F = ℏ 2 m Ω where m is its mass and Ω its natural frequency. However, when I try to derive it with simple arguments, I think of the equality: E = 1 2 ℏ Ω = 1 2 m Ω 2 x Z P F ². The quantum harmonic oscillator has an infinite number of energy levels, indexed by the letter n. Z = T r ( e − β H ^) = ∑ n = 0 ∞ n | e − β H ^ | n = ∑ n = 0 ∞ e − β E n. Students of quantum mechanics will recognize the familiar formula for the energy eigenvalues of the quantum harmonic oscillator. E n = ( n + 1 2) ℏ ω.
