The effective theory of fluids at NLO and implications for dark energy
Guillermo Ballesteros
We present the effective theory of fluids at next-to-leading order in derivatives, including an operator that has not been considered until now. The power-counting scheme and its c…

Large tensor-to-scalar ratio and running of the scalar spectral index with Instep Inflation
Guillermo Ballesteros, J. Alberto Casas
If a sizeable tensor-to-scalar ratio ~0.1 turns out to be detected and a negative running of the scalar spectral index ~0.01 is significantly required by the data, the vast majorit…

Effects of modified gravity on B-mode polarization
Luca Amendola, Guillermo Ballesteros, Valeria Pettorino
We explore the impact of modified gravity on B-modes, identifying two main separate effects: lensing and propagation of tensor modes. The location of the inflationary peak of the B…
