Preheating, Thermalization and Supergravity
Lev Kofman
This contribution to the proceedings collects new recent results on preheating after inflation. We discuss tachyonic preheating in the SUSY motivated hybrid inflation; development…
Dynamics of Symmetry Breaking and Tachyonic Preheating
Gary Felder, Juan Garcia-Bellido, Patrick B. Greene +3
We reconsider the old problem of the dynamics of spontaneous symmetry breaking using 3d lattice simulations, and develop a theory of tachyonic preheating, which occurs due to the s…
The Development of Equilibrium After Preheating
Gary Felder, Lev Kofman
We present a fully nonlinear study of the development of equilibrium after preheating. Preheating is the exponentially rapid transfer of energy from the nearly homogeneous inflaton…
Superconformal Symmetry, Supergravity and Cosmology
Renata Kallosh, Lev Kofman, Andrei Linde +1
We introduce the general N=1 gauge theory superconformally coupled to supergravity. The theory has local SU(2,2|1) symmetry and no dimensional parameters. The superconformal origin…
Inflation After Preheating
Gary Felder, Lev Kofman, Andrei Linde +1
Preheating after inflation may lead to nonthermal phase transitions with symmetry restoration. These phase transitions may occur even if the total energy density of fluctuations pr…
On the Theory of Fermionic Preheating
Patrick B. Greene, Lev Kofman
In inflationary cosmology, the particles constituting the Universe are created after inflation due to their interaction with moving inflaton field(s) in the process of preheating.…
