Cosmology of the string derived flipped
Ignatios Antoniadis, Dimitri V. Nanopoulos, John Rizos
We study the cosmology of a string derived supersymmetric flipped model in the context of free-fermionic heterotic constructions that allow full calculability of the effect…
Building Models of Inflation in No-Scale Supergravity
John Ellis, Marcos A. G. Garcia, Natsumi Nagata +3
After reviewing the motivations for cosmological inflation formulated in the formalism of supersymmetry, we argue that the appropriate framework is that of no-scale supergravity. W…
Non-Oscillatory No-Scale Inflation
John Ellis, Dimitri V. Nanopoulos, Keith A. Olive +1
We propose a non-oscillatory no-scale supergravity model of inflation (NO-NO inflation) in which the inflaton does not oscillate at the end of the inflationary era. Instead, the Un…
Primordial Black Holes from No-Scale Supergravity
Dimitri V. Nanopoulos, Vassilis C. Spanos, Ioanna D. Stamou
We calculate the primordial black hole abundance in the context of a Wess-Zumino type no-scale supergravity model. We modify the Kähler potential, by adding an extra exponential te…
Supercritical String Cosmology drains the Swampland
John Ellis, Nick Mavromatos, Dimitri Nanopoulos
The First and Second Swampland Conjectures (FSC & SSC) are substantially modified in non-critical string cosmology, in which cosmic time is identified with the time-like Liouville…
Phenomenology and Cosmology of No-Scale Attractor Models of Inflation
John Ellis, Dimitri V. Nanopoulos, Keith A. Olive +1
We have recently proposed attractor models for modulus fixing, inflation, supersymmetry breaking and dark energy based on no-scale supergravity. In this paper we develop phenomenol…
