Cosmic expansion from boson and fermion fields
  This paper consists in analyzing an action that describes boson and fermion
fields minimally coupled to the gravity and a common matter field. The
self-interaction potentials of the fields are not chosen a priori but from the
Noether symmetry approach. The Noether forms of the potentials allow the boson
field to play the role of dark energy and matter and the fermion field to
behave as standard matter. The constant of motion and the cyclic variable
associated with the Noether symmetry allow the complete integration of the
field equations, whose solution produces a Universe with alternated periods of
accelerated and decelerated expansion.
