Quantum modes around a scalar-tensor black hole: breakdown of the normalization conditions
F. G. Alvarenga, A. B. Batista, J. C. Fabris +1
Black holes arising in the context of scalar-tensor gravity theories, where the scalar field is non-minimally coupled to the curvature term, have zero surface gravity. Hence, it is…

Troubles with quantum anisotropic cosmological models: loss of unitarity
F. G. Alvarenga, A. B. Batista, J. C. Fabris +1
The anisotropic Bianchi I cosmological model coupled with perfect fluid is quantized in the minisuperspace. The perfect fluid is described by using the Schutz formalism which allow…
