In quantum mechanics, an eigenstate is a specific state where a measurable property, such as energy, has a definite value.
-
And this is an eigenstate of energy with slightly less energy.

If I project it onto an eigenstate of X, that gives me the wave function PSI of X.
-
Once excited, it will tend to radiatively recombine to the same spin eigenstate.

Top-down action occurs in the quantum measurement process through the collapse of the wave function to an eigenstate of a chosen measurement basis.
Academic text (2006) -
Bohr said that the wavefunction collapses and the state is now an eigenstate of the measurement just made.

Etymology
Eigenstate comes from the German eigen, meaning 'own' or 'self', and the English word state, meaning 'condition'. So an eigenstate is the system's 'own state' with a specific value that can be measured, which is why it names a quantum state that gives a definite result when measured.
