Query: Hybrid Quintessential Inflation   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.
