Oscillons during Dirac-Born-Infeld preheating
Oscillons are long-lived, localized, oscillating nonlinear excitations of a real scalar field which can be abundantly produced during preheating after inflation. We give the first (3+1)-dimensional simulation for the oscillon formation during preheating with noncanonical kinetic terms, e.g. the Dira...
