Casimir effect and the quantum vacuum
Abstract
In discussions of the cosmological constant, the Casimir effect is often invoked as decisive evidence that the zeropoint energies of quantum fields are “real.” On the contrary, Casimir effects can be formulated and Casimir forces can be computed without reference to zeropoint energies. They are relativistic, quantum forces between charges and currents. The Casimir force (per unit area) between parallel plates vanishes as α, the fine structure constant, goes to zero, and the standard result, which appears to be independent of α, corresponds to the α→∞ limit.
