Dilaton cosmology and phenomenology
M. Gasperini
This paper is dedicated to Gabriele Veneziano on his 65th birthday. Most of the results reported here are known results, due to Gabriele, or obtained in collaboration with him, or…
Scalar fluctuations in dilatonic brane-worlds
V. Bozza, M. Gasperini, G. Veneziano
We derive and solve the full set of scalar perturbation equations for a class of five-dimensional brane--world solutions, with a dilaton scalar field coupled to the bulk cosmologic…
Gravitational Radiation from String Cosmology
R. Brustein, M. Gasperini, M. Giovannini +1
A spectrum of relic stochastic gravitational radiation, strongly tilted towards high frequencies, and characterized by two basic parameters is shown to emerge in a class of string…
Amplification of Vacuum Fluctuations in String Cosmology Backgrounds
M. Gasperini
Inflationary string cosmology backgrounds can amplify perturbations in a more efficient way than conventional inflationary backgrounds, because the perturbation amplitude may grow…
