LazyTB: Extended LTB-solutions with Multiple Interacting Fluids
Kimmo Kainulainen, Enrico Schiappacasse, Linda Tenhu +1
We present a low entry barrier numerical code LazyTB that solves the Einstein equations in the ADM-formulation for a general spherically symmetric problem with an arbitrary number…

Tachyonic production of dark relics: classical lattice vs. quantum 2PI in Hartree truncation
Kimmo Kainulainen, Sami Nurmi, Olli Väisänen
We study the out-of-equilibrium production of non-minimally coupled self-interacting scalar dark matter during reheating using classical lattice simulations. The outcomes of the cl…
