Quintessential inflation with a trap and axionic dark matter
Konstantinos Dimopoulos, Mindaugas Karčiauskas, Charlotte Owen
We study a new model of quintessential inflation which is inspired by supergravity and string theory. The model features a kinetic pole, which gives rise to the inflationary platea…
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…
Modelling Inflation with a Power-law Approach to the Inflationary Plateau
Konstantinos Dimopoulos, Charlotte Owen
A new family of inflationary models is introduced and analysed. The behaviour of the parameters characterising the models suggest preferred values, which generate the most interest…
How Thermal Inflation can save Minimal Hybrid Inflation in Supergravity
Konstantinos Dimopoulos, Charlotte Owen
Minimal hybrid inflation in supergravity has been ruled out by the 2015 Planck observations because the spectral index of the produced curvature perturbation falls outside observat…
