Revisiting the two-body problem in Yukawa gravity and in a gravitational extension of the Buckingham potential

E. A. Gallegos, R. Perca Gonzales, J. F. Jesus

We revisit the Keplerian-like parametrization of the two-body problem in Yukawa gravity studied in the literature. Some inconsistencies, which spoil Bertrand's theorem, observed in…

Semiclassical resolution of the black hole singularity inspired in the minimal uncertainty approach

Brayan Melchor, Rolando Perca, Wilfredo Yupanqui

We propose a new lapse function that simplifies the Hamiltonian constraint, describing the interior of the black hole in terms of the Ashtekar-Barbero variables, into a more straig…
