Matter bounce loop quantum cosmology from gravity

SD Odintsov, VK Oikonomou - Physical Review D, 2014 - APS
Using the reconstruction method, we investigate which F (R) theories, with or without the
presence of matter fluids, can produce the matter bounce scenario of holonomy corrected …

Reconstruction of cosmic history from a simple parametrization of

SKJ Pacif, R Myrzakulov, S Myrzakul - International Journal of …, 2017 - World Scientific
In this paper, we propose a simple parametrization of the Hubble parameter (HP) H in order
to explain the late-time cosmic acceleration. We show that our proposal covers many models …

Late-time acceleration due to a generic modification of gravity and the Hubble tension

SA Adil, MR Gangopadhyay, M Sami, MK Sharma - Physical Review D, 2021 - APS
We consider a scenario of modified gravity, which is generic to late-time acceleration,
namely, acceleration in the Jordan frame and no acceleration in the Einstein frame. The …
