Simulating the Big Bang Speaker(s): Andrei Frolov
Abstract: At the end of inflation, dynamical instability can rapidly deposit the energy of homogeneous cold inflation into excitations of other fields. This process (known as preheating) essentially starts the hot big bang as we know it. I will present simulations of several preheating models using a new nume... read more

A Singularity Problem with f(R) Dark Energy Speaker(s): Andrei Frolov
Abstract: I point out that there is a curvature singularity problem appearing on non-linear level that generally plagues f(R) models that modify Einstein gravity in the infrared. It is caused by the fact that for the effective scalar degree of freedom, the curvatur
