    • Constraints on Holographic Multifield Inflation and Models Based on the Hamilton-Jacobi Formalism 
      Achúcarro, Ana; Céspedes, Sebastián; Davis, Anne Christine; Palma, Gonzalo A. (American Physical Society, 2019)
      In holographic inflation, the 4D cosmological dynamics is postulated to be dual to the renormalization group flow of a 3D Euclidean conformal field theory with marginally relevant operators. The scalar potential of the 4D ...
    • 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 ...
