A new approach in classical Klein-Gordon cosmology: "Small Bangs", inflation and Dark Energy
Eleni-Alexandra Kontou, Nicolai Rothe
In this work, we analyze the cosmological model in which the expansion is driven by a classical, free Klein-Gordon field on a flat, four-dimensional Friedmann-Lemaître-Robertson-Wa…

Cosmological de Sitter Solutions of the Semiclassical Einstein Equation
Hanno Gottschalk, Nicolai Rothe, Daniel Siemssen
Exponentially expanding space-times play a central role in contemporary cosmology, most importantly in the theory of inflation and in the Dark Energy driven expansion in the late u…

Special cosmological models derived from the semiclassical Einstein equation on flat FLRW space-times
Hanno Gottschalk, Nicolai Rothe, Daniel Siemssen
This article presents numerical work on a special case of the cosmological semiclassical Einstein equation (SCE). The SCE describes the interaction of relativistic quantum matter b…
