    • Features of heavy physics in the CMB power spectrum 
      Achúcarro, Ana; Gong, Jinn-Ouk; Hardeman, Sjoerd; Palma Quilodrán, Gonzalo; Patil, Subodh P. (Elsevier, 2011-01)
      The computation of the primordial power spectrum in multi-field inflaation models requires us to correctly account for all relevant interactions between adiabatic and non-adiabatic modes around and after horizon crossing. ...
    • The hand-made tail: non-perturbative tails from multifield inflation 
      Achúcarro, Ana; Céspedes, Sebastián; Davis, Anne-Christine; Palma Quilodrán, Gonzalo Alejandro (Springer, 2022)
      It is becoming increasingly clear that large but rare fluctuations of the primordial curvature field, controlled by the tail of its probability distribution, could have dramatic effects on the current structure of the ...
