Energy Eigenstates
Fock states are eigenstates of the Hamiltonian of the field:
where is the energy eigenvalue corresponding to . When we put in the expression for the Hamiltonian we get:
Therefore energy of the state is given by where is the frequency of the field. Note that even at the energy does not vanish. This is the zero-point energy.

Famous quotes containing the word energy:
“The persons who constitute the natural aristocracy, are not found in the actual aristocracy, or, only on its edge; as the chemical energy of the spectrum is found to be greatest just outside of the spectrum.”
—Ralph Waldo Emerson (1803–1882)
