Old ideas and new twists in string cosmology
Massimo Giovannini
Some of the phenomenological implications of string cosmological models are reviewed, with particular attention to the spectra of the tensor, scalar and vector modes of the geometr…
Primordial Magnetic Fields and Stochastic GW Backgrounds
Massimo Giovannini
Operating resonant mass detectors set interesting bounds on diffused backgrounds of gravitational radiation and in the next five years the wide-band interferometers will also look…
Magnetogenesis, variation of gauge couplings and inflation
Massimo Giovannini
The interplay among the possible variation of gauge coupling and the inflationary dynamics is investigated in a simplified toy model. Depending upon various parameters (scalar mass…
Primordial magnetic fields
Massimo Giovannini
Large scale magnetic fields represent a triple point where cosmology, high-energy physics and astrophysics meet for different but related purposes. After reviewing the implications…
Graviphoton and graviscalars delocalization in braneworld scenarios
Massimo Giovannini
A manifestly gauge-invariant theory of gravitational fluctuations of brane-world scenarios is discussed. Without resorting to any specific gauge choice, a general method is present…
Inflationary magnetogenesis from dynamical gauge couplings
Massimo Giovannini
The evolution of the gauge coupling is modelled using a scalar degree of freedom whose homogeneous and inhomogeneous modes evolve from an ordinary inflationary phase to the subsequ…
