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…
Adiabaticity and gravity theory independent conservation laws for cosmological perturbations
Antonio Enea Romano, Sander Mooij, Misao Sasaki
We carefully study the implications of adiabaticity for the behavior of cosmological perturbations. There are essentially three similar but different definitions of non-adiabaticit…
