Quantum Cosmology of Fab Four John Theory with Conformable Fractional Derivative
Isaac Torres, Júlio César Fabris, Oliver Fabio Piattella +1
We study a quantization via fractional derivative of a nonminimal derivative coupling cosmological theory, namely, the Fab Four John theory. Its Hamiltonian version presents the is…

Bouncing and Cyclic Quantum Primordial Universes and the Ordering Problem
Isaac Torres, Júlio César Fabris, Oliver Fabio Piattella
In a Bohmian quantum cosmology scenario, we investigate some quantum effects on the evolution of the primordial universe arising from the adoption of an alternative non-trivial ord…

Classical and quantum cosmology of Fab Four John theories
Isaac Torres, Júlio César Fabris, Oliver Fabio Piattella
We present here a quantum cosmological model with Bohm-de Broglie interpretation of the theory described by a combination of two terms of the Fab Four cosmological theory. The firs…
