Reheating in No-Scale Models of Inflation
Ignatios Antoniadis, John Ellis, Dimitri V. Nanopoulos +2
Analogously to the suppression of inflaton decays into conformally-coupled scalar fields in the original Starobinsky model of inflation, inflaton decays to Standard Model…
Ultraviolet completion of Starobinsky inflation
Ignatios Antoniadis, Chrysoula Markou, Dimitri V. Nanopoulos
We construct an supergravity action whose bosonic part contains an arbitrary function of the scalar curvature, the so-called gravity. As in supergravity, it ca…
On the Potential of Microtubules for Scalable Quantum Computation
Nick E. Mavromatos, Andreas Mershin, Dimitri V. Nanopoulos
We examine the quantum coherence properties of tubulin heterodimers arranged into the protofilaments of cytoskeletal microtubules. In the physical model proposed by the authors, th…
--Inflation Derived from 4d Strings, the Role of the Dilaton, and Turning the Swampland into a Mirage
Ignatios Antoniadis, Dimitri V. Nanopoulos, Keith A. Olive
Based on a previously derived superstring model possessing a cosmological sector that mimics Starobinsky inflation, we analyze several questions addressed in the recent literature:…
Deformations of Starobinsky Inflation in No-Scale SU(5) and SO(10) GUTs
John Ellis, Marcos A. G. Garcia, Natsumi Nagata +2
The original Starobinsky model of inflation is consistent with Planck and other measurements of the CMB, but recent results from the ACT and SPT Collaborations hint that…
How Accidental was Inflation?
Ignatios Antoniadis, John Ellis, Wenqi Ke +2
Data on the cosmic microwave background (CMB) are discriminating between different models of inflation, disfavoring simple monomial potentials whilst being consistent with models w…
