Towards a model of Quintessential Inflation
K. Dimopoulos
A model of quintessential inflation is presented, which manages to achieve the requirements of both inflation and quintessence with natural values of the mass-scales and parameters…
Large-Scale Primordial Magnetic Fields from Inflation and Preheating
Ola Tornkvist, Anne-Christine Davis, Konstantinos Dimopoulos +1
We consider models in which the (transverse) photon mass is non-zero during inflation and drops to zero non-adiabatically at the end of inflation. Through this process, vacuum fluc…
Primordial Spectrum of Gauge Fields from Inflation
Anne-Christine Davis, Konstantinos Dimopoulos, Tomislav Prokopec +1
We show that conformal invariance of gauge fields is naturally broken in inflation, having as a consequence amplification of gauge fields. The resulting spectrum of the field stren…
