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…

Zero temperature black holes and the failure of semi-classical analysis
F. G. Alvarenga, A. B. Batista, J. C. Fabris +1
The extreme Reissner-Nordström black holes have zero surface gravity. However, a semi-classical analysis seems to be ill-definite for these objects and apparently no notion of temp…
