The idea of a quantum harmonic oscillator and its associated energy can apply to either an atom or a subatomic particle. In ordinary atomic physics, the zero-point energy is the energy associated with the ground state of the system.
Quantum mechanics predicts the existence of what are usually called ''zero-point'' energies for the strong, the weak and the electromagnetic interactions, where ''zero-point'' refers to the energy of the system at temperature T=0, or the lowest quantized energy level of a quantum mechanical system.

30 cze 2023 · Assume that the particle can move freely between two endpoints \(x = 0\) and \(x = L\), but cannot penetrate past either end. This is equivalent to a potential energy dependent on x with \[V(x)=\begin{cases} 0 & 0\leq x\leq L \\ \infty & x< 0 \; and\; x> L \end{cases}\label{3.5.2}\] This potential is represented in Figure \(\ref{3.5.1}\).
21 maj 2024 · The zero-point energy is a small amount of energy that exists throughout all space. It is also known as the vacuum energy. Put differently, the zero-point energy is the lowest possible energy that a quantum mechanical physical system may have, otherwise known as the energy of the ground state.
1 paź 2024 · Zero-point energy results from principles of quantum mechanics, the physics of subatomic phenomena. Should the molecules ever come completely to rest, their component atoms would be precisely located and would simultaneously have precisely specified velocities, namely, of value zero.
4 sie 2021 · Physical phenomena that we usually ascribe to a zero-point energies are actually nothing but the effect in the difference between two energies, not an effect due to a single energy being zero or not. For example, the Casimir effect is not due to the zero-point energy.
