Gauss-Bonnet-coupled Quintessential Inflation
Carsten van de Bruck, Konstantinos Dimopoulos, Chris Longden +1
We study in detail a new model of quintessential inflation where the inflaton field is coupled to the Gauss-Bonnet term. This coupling ensures that the variation of the field is ke…
Ultra slow-roll inflation demystified
Konstantinos Dimopoulos
Ultra-slow-roll (USR) inflation is a new mode of inflation which corresponds to the occasions when the inflaton field must traverse an extremely flat part of the scalar potential,…
Loop inflection-point inflation
Konstantinos Dimopoulos, Charlotte Owen, Antonio Racioppi
A novel inflection-point inflation model is analysed. The model considers a massless scalar field, whose self-coupling's running is stabilised by a non-renormalisable operator. The…
Quintessential Inflation with -attractors
Konstantinos Dimopoulos, Charlotte Owen
A novel approach to quintessential inflation model building is studied, within the framework of -attractors, motivated by supergravity theories. Inflationary observables are in…
Thermal Inflation with a Thermal Waterfall Scalar Field Coupled to a Light Spectator Scalar Field
Konstantinos Dimopoulos, David H. Lyth, Arron Rumsey
A new model of thermal inflation is introduced, in which the mass of the thermal waterfall field is dependent on a light spectator scalar field. Using the formalism, the "end…
