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…
Quantum cosmology with k-Essence theory
C. R. Almeida, J. C. Fabris, F. Sbisá +1
A class of -Essence cosmological models, with a power law kinetic term, is quantised in the mini-superspace. It is shown that for a specific configuration, corresponding to a pr…
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…
