Pole N-flation

Understand

A second order pole in the scalar kinetic term can lead to a class of inflation models with universal predictions referred to as pole inflation or $\alpha$-attractors.

• While this kinetic structure is ubiquitous in supergravity effective field theories, realising a consistent UV complete model in e.g.
• string theory is a non-trivial task.
• For one, one expects quantum corrections arising in the vicinity of the pole which may spoil the typical attractor dynamics.
