Super-inflation and generation of first order vector perturbations in
  ELKO
  In this work we construct a model where the first order vector perturbations
can be generated during inflationary expansion. For the non-standard spinors,
known as ELKO, we show that the components of the first order perturbed
energy-momentum tensor of the ELKO is non-zero for pure vector part of the
metric perturbation ($B_{i}$). We show that vector perturbations do not decay
in the super-Hubble scale and for a specific super-inflation background model
we show that the vector perturbations are nearly scale invariant, while its
amplitude is smaller than the primordial scalar perturbations. We also comment
on the generation of vorticity.
