High-energy effects on the spectra of cosmological perturbations in braneworld cosmology |
We focus on the cosmological evolution of scalar and tensor perturbations in the Randall-Sundrum single brane model. In this model, there are mainly two high-energy effects, the modification of Friedmann equation and excitation of Kaluza-Klein modes. Using physically plausible initial conditions, we solve numerically the evolution equations of scalar and tensor perturbations and discuss resultant spectra of the curvature perturbation and the gravitational waves. |
