Aspects of supersymmetry breaking driven inflation in orbifold models
G. A. Diamandis, K. Kaskavelis, A. B. Lahanas +1
We consider gravitationally induced corrections to inflaton potentials driven by supersymmetry breaking in a five-dimensional supergravity, compactified on a orbifold.…

Multi-field inflation from a higher derivative N = 1 Supergravity model
G. A. Diamandis, B. C. Georgalas, K. Kaskavelis +1
We study the cosmological evolution of a N = 1 supergravity model, dual to a higher derivative supergravity model coupled to scalar fields so that in the Einstein frame the model i…
