Trapped Quintessential Inflation

  title={Trapped Quintessential Inflation},
  author={J. C. Bueno S{\'a}nchez and Konstantinos Dimopoulos},
Quintessential inflation is studied using a string modulus as the inflaton-quintessence field. The modulus begins its evolution at the steep part of its scalar potential, which is due to non-perturbative effects (e.g. gaugino condensation). It is assumed that the modulus crosses an enhanced symmetry point (ESP) in field space. Particle production at the ESP temporarily traps the modulus resulting in a brief period of inflation. More inflation follows, due to the flatness of the potential, since…

Quintessential inflation: A tale of emergent and broken symmetries
Quintessential inflation provides a unified description of inflation and dark energy in terms of a single scalar degree of freedom, the cosmon. We present here a comprehensive overview of this
Higgs inflation with loop corrections in the Palatini formulation
We compare Higgs inflation in the metric and Palatini formulations of general relativity, with loop corrections are treated in a simple approximation. We consider Higgs inflation on the plateau, at a

This is a very comprehensible review of some key issues in Modern Cosmology. Simple mathematical examples and analogies are always used, whenever available. The starting point is the well know Big
