Abstract
We describe simple models of chaotic inflation which appear in the context of
the superconformal approach to supergravity. One of these models describes a
field minimally coupled to gravity, with the standard symmetry breaking
potential łambda^2 (\phi^2-v^2)^2. Depending on the value of v and on initial
conditions for inflation, the spectral index n_s may take any value from 0.97
to 0.93, and the tensor-to-scalar ratio r may span the interval form 0.3 to
0.01. Another model has a quadratic potential m^2\phi^2/2. The mechanism of
moduli stabilization used in these models allows to improve and generalize
several previously considered models of chaotic inflation in supergravity. We
further generalize these models by adding a nonminimal coupling of the inflaton
field to gravity.
