Inflation in the Postmodern Era
Edward W. Kolb
In this lecture I will review some recent progress in improving the accuracy of the calculation of density perturbations resulting from inflation.
GUT Baryogenesis after Preheating
Edward W. Kolb, Andrei Linde, Antonio Riotto
At the end of inflation the universe is frozen in a near zero-entropy state with energy density in a coherent scalar field and must be ``defrosted'' to produce the observed entropy…
Preheating and symmetry restoration in collisions of vacuum bubbles
Edward W. Kolb, Antonio Riotto
In first-order inflation a phase transition is completed by the collisions of expanding true-vacuum bubbles. If bubble collisions produce large numbers of soft scalar particles car…
Eternal annihilations of light photinos
Edward W. Kolb, Antonio Riotto
In a class of low-energy supersymmetry models the photino is a natural dark matter candidate. We investigate the effects of post-freeze-out photino annihilations which can generate…
