Exact solutions for Big Bounce in loop quantum cosmology
Jakub Mielczarek, Tomasz Stachowiak, Marek Szydlowski
In this paper we study the flat (k=0) cosmological FRW model with holonomy corrections of Loop Quantum Gravity. The considered universe contains a massless scalar field and the cos…
Emerging singularities in the bouncing loop cosmology
Jakub Mielczarek, Marek Szydlowski
In this paper we calculate corrections from holonomies in the Loop Quantum Gravity, usually not taken into account. Allowance of the corrections of this kind is…
Relic gravitons from super-inflation
Jakub Mielczarek, Marek Szydlowski
The super-inflationary phase is predicted by the Loop Quantum Cosmology. In this paper we study the creation of gravitational waves during this phase. We consider the inverse volum…
Testing and selection of cosmological models with corrections
Marek Szydlowski, Wlodzimierz Godlowski, Tomasz Stachowiak
In the paper we check whether the contribution of type in the Friedmann equation can be tested. We consider some astronomical tests to constrain the density parameters…
Acceleration of the Universe driven by the Casimir force
Marek Szydlowski, Wlodzimierz Godlowski
We investigate an evolutional scenario of the FRW universe with the Casimir energy scaling like . The Casimir effect is used to explain the vacuum energy differences (i…
Relic gravitons as the observable for Loop Quantum Cosmology
Jakub Mielczarek, Marek Szydlowski
In this paper we investigate tensor modes of perturbations in the universe governed by Loop Quantum Cosmology. We derive the equation for tensor modes and investigate numerically e…
