Primordial Black Holes And Gravitational Waves Based On No-Scale Supergravity
Ioanna D. Stamou
In this paper we present a class of models in order to explain the production of Primordial Black Holes (PBHs) and Gravitational Waves (GWs) in the Universe. These models are based…
Gravitational Waves and Primordial Black Holes from Supersymmetric Hybrid Inflation
Vassilis C. Spanos, Ioanna D. Stamou
We study the effect of supergravity corrections due to a linear and a bilinear term in the Kähler potential, in the context of a supersymmetric hybrid inflation model. By appropria…
Spectrum oscillations from features in the potential of single-field inflation
I. Dalianis, G. P. Kodaxis, I. D. Stamou +2
We study single-field inflationary models with steep step-like features in the potential that lead to the temporary violation of the slow-roll conditions during the evolution of th…
Mechanisms of Producing Primordial Black Holes By Breaking The SU(2,1)/SU(2)U(1) Symmetry
Ioanna D. Stamou
In this paper we present a class of potentials derived by no-scale supergravity in order to explain the production of primordial black holes (PBHs) in the Universe. By breaking the…
