Modular Hybrid Inflation without Flat Directions and the Curvaton
Konstantinos Dimopoulos
I study two-stage hybrid inflation driven by moduli fields, corresponding to flat directions of supersymmetry, lifted by supergravity corrections. The first stage corresponds to a…

Modelling Quintessential Inflation with Branes
Konstantinos Dimopoulos
I discuss why quintessential inflation model-building is more natural in the context of brane cosmology and study the dynamics of a particular model as an example.

Models of Quintessential Inflation
Konstantinos Dimopoulos
A unified approach to quintessence and inflation is investigated with the use of a single scalar field. It is argued that successful potentials have to approximate a combination of…
