Tachyonic Encore: A universal shift of inflationary observables
Diogo S. Gorgulho, Margherita Putti, Rodrigo Gonzalez Quaglia +3
We propose a generic, largely inflaton-potential-independent mechanism in which a light axion spectator, initialized near the hilltop of its potential, reshapes inflationary observ…
ACT, SPT, and chaotic inflation
Renata Kallosh, Andrei Linde, Diederik Roest
We show that the simplest generalization of the chaotic inflation model with nonminimal coupling to gravity provides a good match to the results o…
Axion Stabilization in Modular Cosmology
John Joseph Carrasco, Renata Kallosh, Andrei Linde +1
The invariant -attractor models have plateau potentials with respect to the inflaton and axion fields. The potential in the axion direction is almost exactly…
Non-linear Electrodynamics from Massive Gravity
Thomas Flöss, Diederik Roest, Tom Westerdijk
As a counterpart to the four-fermion interaction, which describes massive vector exchange at low energies, we investigate the low energy effective action of photons under exchange…
Hybrid Goldstone Modes from the Double Copy Bootstrap
Yang Li, Diederik Roest, Tonnis ter Veldhuis
We perform a systematic classification of scalar field theories whose amplitudes admit a double copy formulation and identify two building blocks at 4-point and 13 at 5-point. Usin…
Flavour-kinematics duality for Goldstone modes
Dijs de Neeling, Diederik Roest, Sam Veldmeijer
Three scalar effective field theories have special properties in terms of non-linear symmetries, soft limits and on-shell constructability that arise from their Goldstone nature: t…
