Tachyonic production of dark relics: a non-perturbative quantum study
Kimmo Kainulainen, Olli Koskivaara, Sami Nurmi
We study production of dark relics during reheating after the end of inflation in a system consisting of a non-minimally coupled spectator scalar field and the inflaton. We derive…

Non-equilibrium dynamics of a scalar field with quantum backreaction
Kimmo Kainulainen, Olli Koskivaara
We study the dynamical evolution of coupled one- and two-point functions of a scalar field in the 2PI framework at the Hartree approximation, including backreaction from out-of-equ…

Quantum transport and the phase space structure of the Wightman functions
Henri Jukkala, Kimmo Kainulainen, Olli Koskivaara
We study the phase space structure of exact quantum Wightman functions in spatially homogeneous, temporally varying systems. In addition to the usual mass shells, the Wightman func…
