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.
