Abstract / Description of output
A model is presented in which a single scalar field is responsible for
both primordial inflation at early times and then dark energy at late
times. This field is coupled to a second scalar field which becomes
unstable and starts to oscillate after primordial inflation, thus
driving a reheating phase that can create a high post-inflation
temperature. This model easily avoids overproduction of gravity waves,
which is a problem in the original quintessential inflation model in
which reheating occurs via gravitational particle production.
