Inflationary predictions of double-well, Coleman-Weinberg, and hilltop
  potentials with non-minimal coupling
  We discuss how the non-minimal coupling $\xi\phi^2R$ between the inflaton and
the Ricci scalar affects the predictions of single field inflation models where
the inflaton has a non-zero vacuum expectation value (VEV) $v$ after inflation.
We show that, for inflaton values both above the VEV and below the VEV during
inflation, under certain conditions the inflationary predictions become
approximately the same as the predictions of the Starobinsky model. We then
analyze inflation with double-well and Coleman-Weinberg potentials in detail,
displaying the regions in the $v$-$\xi$ plane for which the spectral index
$n_s$ and the tensor-to-scalar ratio $r$ values are compatible with the current
observations. $r$ is always larger than 0.002 in these regions. Finally, we
consider the effect of $\xi$ on small field inflation (hilltop) potentials.
