Non-minimally assisted chaotic inflation
  Conventional wisdom says that a chaotic inflation model with a power-law
potential is ruled out by the recent Planck-BICEP/Keck results. We find,
however, that the model can be assisted by a non-minimally coupled scalar field
and still provides a successful inflation. Considering a power-law chaotic
inflation model of the type $V\sim \varphi^n$ with $n=\{2, 4/3, 1, 2/3, 1/3\}$,
we show that $n=1/3$ ($n=\{2/3, 1/3\}$) may be revived with the help of the
quadratic (quartic) non-minimal coupling of the assistant field to gravity.
