Periodic Analogs of Multiple Black Holes Solutions
Omar E. Ortiz, Javier Peraza
In this article, we extend the numerical studies developed in [arXiv:2210.12898] to construct periodic stationary axisymmetric solutions containing multiple horizons in each fundam…
Periodic analogues of the Kerr solutions: a numerical study
Javier Peraza, Martín Reiris, Omar E. Ortiz
In recent years black hole configurations with non standard topology or with non-standard asymptotic have gained considerable attention. In this article we carry out numerical inve…
Size, angular momentum and mass for objects
Pablo Anglada, M. E. Gabach-Clement, Omar E. Ortiz
We obtain a geometrical inequality involving the ADM mass, the angular momentum and the size of an ordinary, axially symmetric object. We use the monotonicity of the Geroch quasi-l…
The inequality between size and charge in spherical symmetry
Pablo Anglada, Sergio Dain, Omar E. Ortiz
We prove that for a spherically symmetric charged body two times the radius is always strictly greater than the charge of the body. We also prove that this inequality is sharp. Fin…
Polarimetric measurements of single-photon geometric phases
O. Ortíz, Y. Yugra, A. Rosario +4
We report polarimetric measurements of geometric phases that are generated by evolving polarized photons along non-geodesic trajectories on the Poincaré sphere. The core of our pol…
Flow force and torque on submerged bodies in lattice-Boltzmann via momentum exchange
Juan P. Giovacchini, Omar E. Ortiz
We present a new derivation of the momentum exchange method to compute the flow force and torque on a submerged body in lattice Boltzmann methods. Our derivation does not depend on…
