Induced gravity, and minimally and conformally coupled scalar fields in Bianchi-I cosmological models
A. Yu. Kamenshchik, E. O. Pozdeeva, A. A. Starobinsky +3
We study the cosmological evolution and singularity crossing in the Bianchi-I universe filled with a conformally coupled scalar field and compare them with those of the Bianchi-I u…
The Born-Oppenheimer Method, Quantum Gravity and Matter
Alexander Yu Kamenshchik, Alessandro Tronconi, Giovanni Venturi
We illustrate and examine diverse approaches to the quantum matter-gravity system which refer to the Born-Oppenheimer (BO) method. In particular we first examine a quantum geometro…
Asymptotically Safe Non-Minimal Inflation
Alessandro Tronconi
We study the constraints imposed by the requirement of Asymptotic Safety on a class of inflationary models with an inflaton field non-minimally coupled to the Ricci scalar. The cri…
Bianchi-I cosmological model and crossing singularities
Alexander Yu. Kamenshchik, Ekaterina O. Pozdeeva, Sergey Yu. Vernov +2
We consider a rather simple method for the description of the Big Bang - Big Crunch cosmological singularity crossing. For the flat Friedmann universe this method gives the same re…
