Zero Energy of Plane-Waves for ELKOs
arXiv:1008.0334 · doi:10.1007/s10714-011-1143-4
Abstract
We consider the ELKO field in interaction through contorsion with its own spin density, and we investigate the form of the consequent autointeractions; to do so we take into account the high-density limit and find plane wave solutions: such plane waves give rise to contorsional autointeractions for which the Ricci metric curvature vanishes and therefore the energy density is equal to zero identically. Consequences are discussed.
