Non-Minimally Coupled Warm Inflation in the Defining Frame
Adrián Casado-Turrión, Paulo B. Ferraz, Mindaugas Karčiauskas +1
Warm inflation in scalar-tensor theories of gravity is investigated in the `defining' frame, where the theory and its parameter values are specified. Translating the result…
Post-Inflationary Constraints on Nonminimally Coupled Quintessential Inflation
Min Gi Park, Seong Chan Park, Tomo Takahashi +1
We investigate quintessential inflation in a nonminimally coupled scalar-tensor theory, parameterizing the post-inflationary radiation abundance independently of the reheating mech…
Axion Inflation with a Massive Abelian Gauge Field
Ricardo Z. Ferreira, Alessio Notari, José Jaime Terente Díaz
An axial coupling between an inflaton and an Abelian gauge field can trigger the tachyonic amplification of one gauge-field helicity. For a massless vector, modes with physical mom…
Post-Newtonian Constraints on Scalar-Tensor Gravity
Alexandros Karam, Samuel Sánchez López, José Jaime Terente Díaz
Solar-System constraints on a general scalar-tensor theory with generic non-minimal coupling function, non-canonical kinetic function, and scalar potential, are investigated in bot…
