The Art of Lattice and Gravity Waves from Preheating
Zhiqi Huang
The nonlinear dynamics of preheating after early-Universe inflation is often studied with lattice simulations. In this work I present a new lattice code HLATTICE. It differs from p…

Non-Gaussian Spikes from Chaotic Billiards in Inflation Preheating
J. Richard Bond, Andrei V. Frolov, Zhiqi Huang +1
A new class of non-Gaussian curvature fluctuations ζ_{pr} (\bx) \equiv δN(χ_i) arises from the post-inflation preheating behaviour of a non-inflaton field χ_i. Its billiard-like ch…

Cosmological Fluctuations from Infra-Red Cascading During Inflation
Neil Barnaby, Zhiqi Huang, Lev Kofman +1
We propose a qualitatively new mechanism for generating cosmological fluctuations from inflation. The non-equilibrium excitation of interacting scalar fields often evolves into inf…
