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…
Deforming the Starobinsky model in ghost-free higher derivative supergravities
G. A. Diamandis, B. C. Georgalas, K. Kaskavelis +2
We consider higher derivative supergravities that are dual to ghost-free supergravity theories in the Einstein frame. The duality is implemented by deforming the Kähler funct…
Inflation in supergravity with non-minimal superpotentials
G. A. Diamandis, B. C. Georgalas, K. Kaskavelis +3
We investigate the cosmological inflation in a class of supergravity models that are generalizations of non-supersymmetric models. Although such models have been extensively…
Heavy quarks in a magnetic field
Elias Kiritsis, George Pavlopoulos
The motion of a heavy charged quark in a magnetic field is analyzed in the vacuum of strongly coupled CFT. The motion of the quark is dissipative. It moves in spiral until it event…
