Zero point fluctuations of the electromagnetic radiation field have profound effects on the electronic states of atoms and molecules. Vacuum fluctuations of the photonic radiation field stimulate the spontaneous decay of excited states of atoms (spontaneous emission), shift atomic energy levels (Lamb Shift), and allow nearby atoms and molecules to couple via dipole-dipole interactions (van der Waals interactions, Casimir effect, super radiance, Förster resonance energy transfer).
