The semiclassical backreaction equations are solved in closed Robertson-Walker
spacetimes containing a positive cosmological constant and a conformally coupled massive …

Most of the phenomenology of loop quantum gravity in the cosmological sector is based on
the so-called holonomy correction to the Hamiltonian constraint. It straightforwardly modifies …

Classical and quantum Friedmann-Lemaître-Robertson-Walker universes filled with
noninteracting radiation and dust fluids are considered in the framework of Hořava-Lifshitz …

Using the Schwarzschild metric as a rudimentary toy model, we pedagogically revisit the
curious prediction that the mass of a classical black hole in a constant temperature thermal …

If the spatial sections of the Universe are positively curved, extrapolating the inflationary
stage backward in time inevitably leads to a classical bounce. This simple scenario, non …

The inflationary and pre-inflationary evolution of scalar modes of cosmological perturbations
in a closed universe is analyzed for a loop quantum cosmology model with an inflationary …

We investigate the realization of a nonsingular bounce within the framework of
Myrzakulov\(F (R, T)\) gravity. This modified gravitational theory uses a non-special …

We study quasi-matter bounce cosmology in light of Planck cosmic microwave background
angular anisotropy measurements along with the BICEP2/Keck Array data. We propose a …
