The rapid-turn inflationary attractor
  We prove the existence of a general class of rapidly turning two-field
inflationary attractors. By only requiring a large, slowly varying turn rate,
we solve the system completely without specifying any metric or potential, and
prove the linear stability of the solution. Several recently studied turning
inflation models, including hyperinflation, side-tracked inflation, and a flat
field-space model, turn out to be examples of this general class of attractor
solutions. Very rapidly turning models are of particular interest since they
can be compatible with the swampland conjectures, and we show that the
solutions further simplify in this limit.
