The abstract, sentence by sentence

arXiv listing abstract v3. Results and the main claim are underlined; show every role.

We study both oscillating and inflating curvaton scenarios when the curvaton mechanism is caused by a hybrid potential. The source of the curvature perturbation is the inhomogeneous phase transition that causes the modulation of the onset of the oscillation. For the supergravity-motivated curvaton there is a possibility of finding natural coincidence of the energy density that is needed to affect non-Gaussianity in the curvaton scenario.

The paper

Original abstract

We study both oscillating and inflating curvaton scenarios when the curvaton mechanism is caused by a hybrid potential. The source of the curvature perturbation is the inhomogeneous phase transition that causes the modulation of the onset of the oscillation. For the supergravity-motivated curvaton there is a possibility of finding natural coincidence of the energy density that is needed to affect non-Gaussianity in the curvaton scenario.

Audible curvaton: modulated phase transition as the origin of large-scale curvature perturbations and gravitational wave anisotropies
astro-ph.CO 2026-10 accept novelty 7.0 of 10

A spectator field modulating a post-inflationary first-order phase transition can generate the observed primordial curvature perturbations and a correlated stochastic gravitational wave background with enhanced anisotropies.
Primordial Black Holes from the inflating curvaton
hep-ph 2012-11 conditional novelty 5.0 of 10

A two-stage inflation model in which the curvaton field inflates can generate primordial black holes with masses between 10^14 and 10^38 grams, with the mass set by the number of curvaton e-foldings.

[Our model is very different from the recently proposed “hybrid curvaton” model of Dimopoulos et al [ref] where the curvaton field has a waterfall-type potential, so that oscillations of the curvaton field are triggered by a tachyonic instability.]
