Quantum electron energy states for electron are found using the electron quantum Hamiltonian, which is generally composed of kinetic (-ħ ∇ /2me) and potential energy terms (φe). Atomic orbital, a mathematical function describing the wave-like behavior of either an electron or a pair of electrons in an atom, can be found from the Schrödinger equation with this electron Hamiltonian. Hydrogen-like atoms (a nucleus and an electron) allow for closed-form solution to Schrödinger e… WebApr 26, 2024 · Phonons are the energy quanta of lattice vibrations in crystalline solids. Their excitation allows heat to travel through a solid, but scattering processes slow down this …
