Universality and scaling in multi-field -attractor preheating
Oksana Iarygina, Evangelos I. Sfakianakis, Dong-Gang Wang +1
We explore preheating in multi-field models of inflation in which the field-space metric is a highly curved hyperbolic manifold. One broad family of such models is called -attra…
Constraints on holographic multi-field inflation and models based on the Hamilton-Jacobi formalism
Ana Achucarro, Sebastian Cespedes, Anne-Christine Davis +1
In holographic inflation, the cosmological dynamics is postulated to be dual to the renormalization group flow of a Euclidean conformal field theory with marginally relev…
Hypernatural inflation
Andrei Linde, Dong-Gang Wang, Yvette Welling +2
We constructed a model of natural inflation in the context of -attractor supergravity, in which both the dilaton field and the axion field are light during inflation, and the in…
