    • B modes and the sound speed of primordial fluctuations 
      Palma Quilodrán, Gonzalo; Soto, Alex (Amer Physical Soc, 2015)
      It was recently shown that a large value of the tensor to scalar ratio r implies a constraint on the minimum value of the sound speed c(s) of primordial curvature perturbations during inflation that is stronger than current ...
    • Consistency relations for sharp features in the primordial spectra 
      Mooij, Sander; Palma Quilodrán, Gonzalo; Panotopoulos, Grigoris; Soto, Alex (IOP Press, 2015)
      We study the generation of sharp features in the primordial spectra within the framework of effective field theory of inflation, wherein curvature perturbations are the consequence of the dynamics of a single scalar degree ...
