Self-resonance preheating in deformed attractor models: Oscillon formation and evolution

It is well known that, in potentials that are quadratic near the minimum but shallower away, such as small $α$ ($\ll M_P^2$) attractors, the inflaton condensate fragments into localized compact objects known as oscillons during self-resonance preheating. In this work we investiga...
