In quantum mechanics, a stationary state is an eigenvector of the Hamiltonian, implying the probability density associated with the wavefunction is independent of time. This corresponds to a quantum state with a single definite energy (instead of a probability distribution of different energies). It is also called energy eigenvector, energy eigenstate, energy eigenfunction, or energy eigenket. It is very similar to the concept of atomic orbital and molecular orbital in chemistry, with some slight differences explained below.

Famous quotes containing the words stationary and/or state:
“It is the dissenter, the theorist, the aspirant, who is quitting this ancient domain to embark on seas of adventure, who engages our interest. Omitting then for the present all notice of the stationary class, we shall find that the movement party divides itself into two classes, the actors, and the students.”
—Ralph Waldo Emerson (1803–1882)
“In days gone by, we were afraid of dying in dishonor or a state of sin. Nowadays, we are afraid of dying fools. Now the fact is that there is no Extreme Unction to absolve us of foolishness. We endure it here on earth as subjective eternity.”
—Jean Baudrillard (b. 1929)
