Rapid-turn inflation in supergravity is rare and tachyonic
Vikas Aragam, Roberta Chiovoloni, Sonia Paban +2
Strongly non-geodesic, or rapidly turning trajectories in multifield inflation have attracted much interest recently from both theoretical and phenomenological perspectives. Most m…
A Scenario for a Singularity-free Generic Cosmological Solution
Giovanni Montani, Roberta Chiovoloni
We develop a scenario for the emergence of a non-singular generic cosmological solution based on the a WKB characterization of one of the two anisotropy degrees of freedom. We inve…
Quantum dynamics of the corner of the Bianchi IX model in WKB approximation
Roberta Chiovoloni, Giovanni Montani, Valerio Cascioli
In this paper we analyse the Bianchi IX Universe dynamics within the corner region associated to the potential term which the spatial curvature induces in the Minisuperspace. The s…
Fat Inflatons, Large Turns and the -problem
Dibya Chakraborty, Roberta Chiovoloni, Oscar Loaiza-Brito +2
It is commonly believed that a successful period of inflation driven by a single or several scalar fields requires a specific hierarchy of masses given by $M_{inf}\ll H \ll M_{heav…
