Inflation and Reheating with a Fermionic Field
  Inflation has long been the accepted paradigm for understanding the early
universe. Most models of inflation have a scalar field acting as the inflaton
particle which decays after inflation during a process called reheating into
standard model (SM) particles. In this work, we consider a fermion as the
inflaton field. Noether symmetry arguments show that an exponentially expanding
universe is possible with a fermion if it is coupled non-minimally to gravity.
We use such a scenario in this model to study both inflation and reheating. We
find relations between the various parameters involved in this model which
include the non-minimal coupling strength $\xi$, the mass $m$ and the Yukawa
coupling $Y$.
