Rapid-turn inflation in supergravity is rare and tachyonic

Strongly non-geodesic, or rapidly turning trajectories in multifield inflation have attracted much interest recently from both theoretical and phenomenological perspectives. Most models with large turning rates in the literature are formulated as effective field theories. In this paper we investigate rapid-turn inflation in supergravity as a first step towards understanding them in string theory. We find that large turning rates can be generated in a wide class of models, at the cost of high…

Revisiting small-scale fluctuations in $\alpha$-attractor models of inflation
Cosmological α–attractors stand out as particularly compelling models to describe inflation in the very early universe, naturally meeting tight observational bounds from cosmic microwave background


Multi-field inflation in high-slope potentials
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
Sound Speed of Primordial Fluctuations in Supergravity Inflation.
This paper studies the realization of slow-roll inflation in N=1 supergravities where inflation is the result of the evolution of a single chiral field and shows that if large non-Gaussianity is observed, supergravity models of inflation would be severely constrained.
Primordial fluctuations and non-Gaussianities in sidetracked inflation
Heavy scalar fields can undergo an instability during inflation as a result of their kinetic couplings with the inflaton. This is known as the geometrical destabilization of inflation, as it relies
Features of heavy physics in the CMB power spectrum
The computation of the primordial power spectrum in multi-field inflation models requires us to correctly account for all relevant interactions between adiabatic and non-adiabatic modes around and
Shift-symmetric orbital inflation: Single field or multifield?
We present a new class of two-field inflationary attractor models, known as `shift-symmetric orbital inflation', whose behaviour is strongly multi-field but whose predictions are remarkably close to
Scaling attractors in multi-field inflation
Multi-field inflation with a curved scalar geometry has been found to support background trajectories that violate the slow-roll, slow-turn conditions and thus have the potential to evade the
Angular inflation in multi-field α-attractors
We explore the dynamics of multi-field models of inflation in which the field-space metric is a hyperbolic manifold of constant curvature. Such models are known as α-attractors and their single-field
Racetrack Inflation
We develop a model of eternal topological inflation using a racetrack potential within the context of type IIB string theory with KKLT volume stabilization. The inflaton field is the imaginary part
Kahler moduli inflation
We show that under general conditions there is at least one natural inflationary direction for the Kahler moduli of type-IIB flux compactifications. This requires a Calabi-Yau which has
Sgoldstino inflation
We discuss the possibility that inflation is driven by the sgoldstino, the superpartner of the goldstino. Unlike in generic supergravity scenarios, the sgoldstino decouples from all other fields in
