Descripción
We introduce a new model for dark energy in the Universe in which a
small cosmological constant is generated by ordinary electromagnetic
vacuum energy. The corresponding virtual photons exist at all
frequencies but switch from a gravitationally active phase at low
frequencies to a gravitationally inactive phase at higher frequencies
via a Ginzburg-Landau type of phase transition. Only virtual photons in
the gravitationally active state contribute to the cosmological
constant. A small vacuum energy density, consistent with astronomical
observations, is naturally generated in this model. We propose possible
laboratory tests for such a scenario based on phase synchronization in
superconductors.
