We study the production of primordial black holes (PBHs) during the preheating stage that follows a chaotic inflationary phase. The scalar fields present in the process are evolved numerically using a modified version of the HLATTICE code. From the output of the numerical simulation, we compute the probability distribution of curvature fluctuations, paying particular attention to sub-horizon scales. We find that in some specific models these modes grow to large amplitudes developing highly non-Gaussian probability distributions. We then calculate PBH abundances using the standard Press-Schechter criterion and find that overproduction of PBHs is likely in some regions of the chaotic preheating parameter space.

Inflaton Self Resonance, Oscillons, and Gravitational Waves in Small Field Polynomial Inflation
For sufficiently small phi0 (below about 0.02 mPl), the inflaton condensate in this polynomial model fragments into long-lived oscillons, producing MHz-GHz gravitational waves and possibly seeding light primordial bla...

Reconstructing Primordial Curvature Perturbations via Scalar-Induced Gravitational Waves with LISA
LISA can reconstruct the primordial curvature power spectrum from scalar-induced gravitational waves, with percent-level precision near the peak and Bayesian tests separating SIGWs from other sources.
