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…

Three examples of quantum dynamics on the half-line with smooth bouncing
Carla Rodrigues Almeida, Hervé Bergeron, Jean Pierre Gazeau +1
This article is an introductory presentation of the quantization of the half-plane based on affine coherent states (ACS). The half-plane is viewed as the phase space for the dynami…

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…
