Coherent states of quantum spacetimes for black holes and de Sitter spacetime
Diego J. Cirilo-Lombardo, Norma G. Sanchez
We provide a group theory approach to coherent states describing quantum space-time and its properties. This provides a relativistic framework for the metric of a Riemmanian space…
Einstein-Born-Infeld gravastar models, dark matter and accretion mechanisms
Diego Julio Cirilo-Lombardo, Carlos Vigh
Gravastar models have recently been proposed as an alternative to black holes, mainly to avoid the pro\-ble\-ma\-tic issues associated with event horizons and singularities. In thi…
Non-Riemmanian geometry, force-free magnetospheres and the generalized Grad-Shafranov equation
Diego Julio Cirilo-Lombardo
The magnetosphere structure of a magnetar is considered in the context of a theory of gravity with dynamical torsion field beyond the standard General Relativity (GR). To this end,…
Von Neumann's Quantization of General Relativity
A. B. Arbuzov, A. Yu. Cherny, D. J. Cirilo-Lombardo +5
Von Neumann's procedure is applied for quantization of General Relativity. We quantize the initial data of dynamical variables at the Planck epoch, where the Hubble parameter coinc…
The Affine Structure of Gravitational Theories: Symplectic Groups and Geometry
Salvatore Capozziello, Diego Julio Cirilo-Lombardo, Mariafelicia De Laurentis
We give a geometrical description of gravitational theories from the viewpoint of symmetries and affine structure. We show how gravity, considered as a gauge theory, can be consist…
The Newman-Janis Algorithm, Rotating Solutions and Einstein-Born-Infeld Black Holes
Diego Cirilo-Lombardo
A new metric is obtained by applying a complex coordinate trans- formation to the static metric of the self-gravitating Born-Infeld monopole. The behaviour of the new metric is typ…
New spherically symmetric monopole and regular solutions in Einstein-Born-Infeld theories
D. J. Cirilo-Lombardo
In this work a new asymptotically flat solution of the coupled Einstein-Born-Infeld equations for a static spherically symmetric space-time is obtained. When the intrinsic mass is…
Rotating charged Black Holes in Einstein-Born-Infeld theories and their ADM mass
Diego Julio Cirilo-Lombardo
In this work, the solution of the Einstein equations for a slowly rotating black hole with Born-Infeld charge is obtained. Geometrical properties and horizons of this solution are…
