  We study the dynamics of two concrete inflationary models, namely Spontaneous
Symmetry Breaking Inflation as well as Loop Inflation. We constrain the
parameters for which a viable inflationary Universe emerges using the latest
PLANCK results of last year, and we give predictions for the duration of
reheating as well as for the reheating temperature after inflation. Our
numerical results show that baryogenesis via leptogenesis may be realized
within the inflationary models considered in this work.
