Anatomy of geometrical destabilization of inflation
Tomasz Krajewski, Krzysztof Turzyński
We study geometrical destabilization of inflation with the aim of determining the fate of excited unstable modes. We use numerical lattice simulations to track the dynamics of both…
(P)reheating and gravitational waves in -attractor models
Tomasz Krajewski, Krzysztof Turzyński
We study post-inflationary evolution in -attractor T-models of inflation. We consider the dynamics of both scalar fields present in these models: the inflaton and the spectator,…
On backreaction effects in geometrical destabilisation of inflation
Oskar Grocholski, Marcin Kalinowski, Maciej Kolanowski +3
We study the geometrical instability arising in multi-field models of inflation with negatively-curved field space. We analyse how the homogeneous background evolves in presence of…
Floquet analysis of self-resonance in single-field models of inflation
Krzysztof Turzyński, Michał Wieczorek
We review 51 models of single-field inflation, paying special attention to the possibility that self-resonance of the unstable inflaton perturbations leads to reheating. We compute…
On preheating in alpha-attractor models of inflation
Tomasz Krajewski, Krzysztof Turzyński, Michał Wieczorek
We study (p)reheating in alpha-attractor T-models of inflation, taking into account both scalar fields present in these models: the inflaton and the spectator. The two-field model…
Geometrical destabilization, premature end of inflation and Bayesian model selection
Sébastien Renaux-Petel, Krzysztof Turzyński, Vincent Vennin
By means of Bayesian techniques, we study how a premature ending of inflation, motivated by geometrical destabilization, affects the observational evidences of typical inflationary…
