Higher-dimensional perturbations of the vacuum energy density
M. Gasperini
The vacuum energy density arising from the broken supersymmetry of the (standard-model) fields living on a brane cannot be fully "off-loaded" to the bulk: even assuming the existen…
Cosmological perturbations across a curvature bounce
M. Gasperini, M. Giovannini, G. Veneziano
String-inspired cosmologies, whereby a non-singular curvature bounce is induced by a general-covariant, -duality-invariant, non-local dilaton potential, are used to study numeri…
The Pre-Big Bang Scenario in String Cosmology
M. Gasperini, G. Veneziano
We review physical motivations, phenomenological consequences, and open problems of the so-called pre-big bang scenario in superstring cosmology.
Sensitivity of spherical gravitational-wave detectors to a stochastic background of non-relativistic scalar radiation
E. Coccia, M. Gasperini, C. Ungarelli
We analyze the signal-to-noise ratio for a relic background of scalar gravitational radiation composed of massive, non-relativistic particles, interacting with the monopole mode of…
On the response of gravitational antennas to dilatonic waves
M. Gasperini
It is pointed out that the coupling of macroscopic test masses to the gravi-dilaton background of string theory is non geodesic, in general, and cannot be parametrized by a Brans-D…
Duality in cosmological perturbation theory
R. Brustein, M. Gasperini, G. Veneziano
Cosmological perturbation equations derived from low-energy effective actions are shown to be invariant under a duality transformation reminiscent of electric-magnetic, strong-weak…
