abstract
Dirac linear spinor fields were obtained from non-linear Heisenberg spinors, in the literature. Here we extend that idea by considering not only Dirac spinor fields but spinor fields in any of the Lounesto's classes. When one starts considering all these classes of fields, the question of providing a classification for the Heisenberg spinor naturally arises. In this work the classification of Heisenberg spinor fields is derived and scrutinized, in its interplay with the Lounesto's spinor field classification.

Wigner multiplets in QFT: from Wigner degeneracy to Elko fields
Under Lorentz covariance, causality, and canonical quantization, the Wigner superposition field is shown to be uniquely realized by the Elko field, which has mass dimension one and Klein-Gordon kinematics.
