Multi-field Inflation in High-Slope Potentials

Understand

We present two families of multi-field potentials that support inflation while satisfying the refined de Sitter and the distance swampland conjectures.

• Both families feature Planck-compatible phenomenology.
• The first is a helix-type potential, in a flat field-space metric, that satisfies the conjectures via a high turning rate.
• This model has a tensor-toscalar ratio close to, but below, the current experimental limits and small non-gaussianities.
