A comparison between Jordan and Einstein frames of Brans-Dicke gravity a la loop quantum cosmology
Michal Artymowski, Yonnge Ma, Xiangdong Zhang
It is well known that the Jordan and Einstein frames are equivalent to each other in classical Brans-Dicke theory, provided that one and the same metric is employed for the physica…

Loop quantum cosmology for nonminimally coupled scalar field
Michal Artymowski, Andrea Dapor, Tomasz Pawlowski
We perform a LQC-quantization of the FRW cosmological model with nonminimally coupled scalar field. Making use of a canonical transformation, we recast the theory in the minimally…
