Disformal transformations as a change of units
Jacopo Fumagalli, Sander Mooij, Marieke Postma
A disformal transformation is a very useful tool to analyze a general effective theory description of inflation. It can for example be used to set the tensor sound speed to unity,…
Global adiabaticity and non-Gaussianity consistency condition
Antonio Enea Romano, Sander Mooij, Misao Sasaki
In the context of single-field inflation, the conservation of the curvature perturbation on comoving slices, , on super-horizon scales is one of the assumptions necessary to…
Consistency relations for sharp inflationary non-Gaussian features
Sander Mooij, Gonzalo A. Palma, Grigoris Panotopoulos +1
If cosmic inflation suffered tiny time-dependent deviations from the slow-roll regime, these would induce the existence of small scale-dependent features imprinted in the primordia…
