Idea

In quantum electrodynamics there is a net force between two conducting but uncharged parallel plates, which is absent in the classical field theory of electromagnetism. This quantum effect is called the Casimir effect.

References

Named after Hendrik Casimir.

Discussion in the context of causal perturbation theory is in

Popular accounts often attribute the Casimir effect to vacuum energy. Discussion that this is false includes
