Multipoint correlators in multifield cosmology
George Panagopoulos, Eva Silverstein
Connected -point amplitudes in quantum field theory are enhanced by a factor of in appropriate regimes of kinematics and couplings, but the non-perturbative analysis of thi…

Primordial Black Holes from non-Gaussian tails
George Panagopoulos, Eva Silverstein
We develop a primordial black hole (PBH) production mechanism, deriving non-Gaussian tails from interacting quantum fields during early universe inflation. The multi-field potentia…
