Pole inflation from non-minimal coupling to gravity

Understand

Transforming canonical scalars to the Einstein frame can give a multi-field generalization of pole inflation (namely, a scalar with a divergent kinetic term) at vanishing field-dependent Planck mass.

• However, to obtain an attractor, the scalar potential must obey certain non-generic conditions.
• These are automatically satisfied in Quantum Field Theories with dimension-less couplings.
• The resulting models of pole inflation have special inflationary predictions determined by the full RG running of couplings.
