Light-like propagation of self-interacting KleinâGordon fields in cosmology
Abstract
It is showed that complex scalar fields with a self-interaction potential may propagate along null geodesics on isotropic flat FriedmannâLemaîtreâRobertsonâWalker universes with different time-dependent scale factors. This effect appears for certain kinds of self-interactions only, for different forms of potentials, and even for the massive case.
