Quantization of a Black-Hole Gravity: geometrodynamics and the quantum phase-space formalism
Carla Rodrigues Almeida, Denis Campos Rodrigues
Quantum gravity is effective in domains where both quantum effects and gravity are essential, such as in the vicinity of space-time singularities. This paper will investigate the q…
Quantum and classical cosmology in the Brans-Dicke theory
Carla R. Almeida, O. Galkina, J. C. Fabris
In this paper we discuss classical and quantum aspects of cosmological models in Brans-Dicke theory. First, we review cosmological bounce solution in Brans-Dicke theory that obeys…
Affine quantisation of the Brans-Dicke theory: Smooth bouncing and the equivalence between the Einstein and Jordan frames
E. Frion, C. R. Almeida
In this work, we present a complete analysis of the quantisation of the classical Brans-Dicke Theory using the method of affine quantisation in the Hamiltonian description of the t…
Cosmological scenarios in quantum cosmology of Brans-Dicke theory of gravity on Einstein and Jordan frames
Carla Rodrigues Almeida, Antônio Brasil Batista, Júlio César Fabris +1
The Hamiltonian of any quantum cosmological model must obey some conditions in order to be self-adjoint, or to admit self-adjoint extensions. We will consider in this paper the sel…
Quantum cosmology of scalar-tensor theories and self-adjointness
C. R. Almeida, A. B. Batista, J. C. Fabris +1
In this paper, the problem of the self-adjointness for the case of a quantum minisuperspace Hamiltonian retrieved from a Brans-Dicke (BD) action is investigated. Our matter content…
New views on classical and quantum Brans-Dicke theory
Júlio C. Fabris, Bertrand Chauvineau, Davi C. Rodrigues +2
The Brans-Dicke action is one of the most natural extensions of the Einstein-Hilbert action. It is based on the introduction of a fundamental scalar field that effectively incorpor…
