WebPrimordial gravitational waves (GWs) carry the imprints of the dynamics of the universe during its earliest stages; this is connected with the isotropic and homogeneous symmetry of the universe. Beside the primordial GWs, the induced GWs generated from enhanced scalar perturbations over low scales as well as from a primordial magnetic field are ... WebA perturbation on the background inflaton potential can lead inflation into the ultraslow-roll stage and can thus remarkably enhance the power spectrum PR(k ) of the primordial curvature perturbation on small scales. Such an enhanced PR(k ) will result in primordial black holes (PBHs), contributing a significant fraction of dark …
