Description
Resonant excitations during inflation can amplify the primordial curvature perturbation within a narrow range of k values. This suggests a novel mechanism to generate Primordial Black Holes (PBHs). We study such resonances within the context of the Running-Mass-Inflation model. Generated PBHs can explain the totality of Dark Matter. The mechanism also predicts enhanced induced Gravitational Waves (GWs) and GWs created by binary BH collisions. They will be observable by future laser interferometers and resonant cavity experiments respectively.
