Novel matter coupling in Einstein gravity
Chunshan Lin, Zygmunt Lalak
A general framework of the novel matter coupling in the Einstein gravity is introduced. We firstly prove that a class of theories whose Hamiltonian constraint is given by an arbitr…
Darkflation -- one scalar to rule them all?
Zygmunt Lalak, Łukasz Nakonieczny
The problem of explaining both inflationary and dark matter physics in the framework of a minimal extension of the Standard Model was investigated. To this end, the Standard Model…
Saddle point inflation from theory
Michal Artymowski, Zygmunt Lalak, Marek Lewicki
We analyse several saddle point inflationary scenarios based on power-law models. We investigate inflation resulting from $f(R) = R + α_n M^{2(1-n)}R^n + α_{n+1}M^{-2n}R^{n+…
Vector fields and Loop Quantum Cosmology
Michal Artymowski, Zygmunt Lalak
In the context of the Loop Quantum Cosmology we have analysed the holonomy correction to the classical evolution of the simplified Bianchi I model in the presence of vector fields.…
