In the framework of Einstein-Yang-Mills theories, we study the gauge Lorentz group and establish a particular correspondence between this case and a certain class of theories with torsion within RiemannCartan space-times. This relation is specia[...]texto impreso
We find a new exact vacuum solution in the framework of the Poincaré Gauge field theory with massive torsion. In this model, torsion operates as an independent field and introduces corrections to the vacuum structure present in General Relativit[...]texto impreso
Ruiz Cembranos, José Alberto ; Gigante Valcarcel, Jorge ; Maldonado Torralba, F. J. | IOP Publishing | 2019-04In this work we study the non-geodesical behaviour of particles with spin 1/2 in Poincare gauge theories of gravity via the WKB method. Within this approach, we calculate the trajectories in a particular Poincare gauge theory, discussing the via[...]texto impreso
A large number of classes of modified theories of gravity have been developed for a long time. They have attracted much attention from physicists, since they show different aspects concerning gravitational interaction. In fact, these aspects may[...]texto impreso
We derive a new exact static and spherically symmetric vacuum solution in the framework of the Poincaré gauge field theory with dynamical massless torsion. This theory is built in such a form that allows to recover General Relativity when the fi[...]texto impreso
Ruiz Cembranos, José Alberto ; Gigante Valcarcel, Jorge ; Maldonado Torralba, F. J. | Multidisciplinary Digital Publishing Institute | 2019-03-14In this work, we review the study of singularities in Poincare gauge theories of gravity. Since one of the most recent studies used the appearance of black hole regions of arbitrary dimension as an indicator of singular behavior, we also give so[...]texto impreso
Ruiz Cembranos, José Alberto ; Gigante Valcarcel, Jorge ; Maldonado Torralba, F. J. | IOP Publishing | 2017-04In this work we have studied the singular behaviour of gravitational theories with non symmetric connections. For this purpose we introduce a new criteria for the appearance of singularities based on the existence of black/white hole regions of [...]texto impreso
Borislavov Vasilea, Teodor ; Ruiz Cembranos, José Alberto ; Gigante Valcarcel, Jorge ; Martín Moruno, María del Prado | Springer | 2017-11-10We revisit the definition and some of the characteristics of quadratic theories of gravity with torsion. We start from a Lagrangian density quadratic in the curvature and torsion tensors. By assuming that General Relativity should be recovered w[...]
