Gravitational Wave Production At The End Of Inflation
Richard Easther, John T. Giblin, Eugene A. Lim
We consider gravitational wave production due to parametric resonance at the end of inflation, or ``preheating''. This leads to large inhomogeneities which source a stochastic back…
Large Non-Gaussianities in Single Field Inflation
Xingang Chen, Richard Easther, Eugene A. Lim
We compute the 3-point correlation function for a general model of inflation driven by a single, minimally coupled scalar field. Our approach is based on the numerical evaluation o…
Stochastic Gravitational Wave Production After Inflation
Richard Easther, Eugene A. Lim
In many models of inflation, the period of accelerated expansion ends with preheating, a highly non-thermal phase of evolution during which the inflaton pumps energy into a specifi…
