Schrödinger (wave) Equation wave functions → stationary states It is an eigenvector of the Hamiltonian, which corresponds to a state with a single definite energy (instead of a quantum superposition of different energies). It is also called energy eigenvector, energy eigenstate, energy eigenfunction, or “orbitals” as in atomic orbitals or molecular orbitals. Time-dependent Time-independent When the Hamiltonian operator acts on a certain wave function Ψ, and the result is proportional to the same wave function Ψ, then Ψ is a stationary state, and the proportionality constant, E, is the energy of the state Ψ. https://en.wikipedia.org/wiki/Stationary_state
