Gauge-independent approach to inflation in quadratic gravity
Adrian Palomares, Ying-li Zhang, Jinsu Kim
We investigate the scalar sector of linear cosmological perturbations in quadratic gravity. Working in the Einstein frame, we derive the equations of motion in a gauge-independent…

An update on adiabatic modes in cosmology and N formalism
Diego Cruces, Cristiano Germani, Adrian Palomares
In this paper, we generalize the Weinberg's procedure to determine the comoving curvature perturbation to non-attractor inflationary regimes. We show that both modes of $\…
