(Slow-)Twisting inflationary attractors
Perseas Christodoulidis, Robert Rosati
We explore in detail the dynamics of multi-field inflationary models. We first revisit the two-field case and rederive the coordinate independent expression for the attractor solut…
Rapid-turn inflation in supergravity is rare and tachyonic
Vikas Aragam, Roberta Chiovoloni, Sonia Paban +2
Strongly non-geodesic, or rapidly turning trajectories in multifield inflation have attracted much interest recently from both theoretical and phenomenological perspectives. Most m…
The Multi-Field, Rapid-Turn Inflationary Solution
Vikas Aragam, Sonia Paban, Robert Rosati
There are well-known criteria on the potential and field-space geometry for determining if slow-roll, slow-turn, multi-field inflation is possible. However, even though it has been…
Multi-field Inflation in High-Slope Potentials
Vikas Aragam, Sonia Paban, Robert Rosati
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…
