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…
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…
Quantum Dew
S. Khlebnikov, I. Tkachev
We consider phase separation in nonequilibrium Bose gas with an attractive interaction between the particles. Using numerical integrations on a lattice, we show that the system evo…
Cosmic strings from preheating
I. Tkachev, S. Khlebnikov, L. Kofman +1
We investigate nonthermal phase transitions that may occur after post-inflationary preheating in a simple model of a two-component scalar field with the effective potential $λ(ϕ_i^…
First-order nonthermal phase transition after preheating
S. Khlebnikov, L. Kofman, A. Linde +1
During preheating after inflation, parametric resonance rapidly generates very large fluctuations of scalar fields. In models where the inflaton field oscillates in a double-we…
