Cosmological applications of gravity
Georgios Kofinas, Emmanuel N. Saridakis
We investigate the cosmological applications of gravity, which is a novel modified gravitational theory based on the torsion invariant and the teleparallel equivalen…
Efficient electroweak baryogenesis by black holes
Georgios Aliferis, Georgios Kofinas, Vasilios Zarikas
A novel cosmological scenario, capable to generate the observed baryon number at the electroweak scale for very small CP violating angles, is presented. The proposed mechanism can…
Conformal Mass in AdS gravity
Dileep P. Jatkar, Georgios Kofinas, Olivera Miskovic +1
We show that the Ashtekar-Magnon-Das (AMD) mass and other conserved quantities are equivalent to the Kounterterm charges in the asymptotically AdS spacetimes that satisfy the Einst…
Dynamical behavior in cosmology
Georgios Kofinas, Genly Leon, Emmanuel N. Saridakis
The class of gravitational modification, based on the quadratic torsion scalar , as well as on the new quartic torsion scalar which is the teleparallel equivale…
Teleparallel equivalent of Gauss-Bonnet gravity and its modifications
Georgios Kofinas, Emmanuel N. Saridakis
Inspired by the teleparallel formulation of General Relativity, whose Lagrangian is the torsion invariant T, we have constructed the teleparallel equivalent of Gauss-Bonnet gravity…
Cosmological solutions and observational constraints on 5-dimensional braneworld cosmology with gravitating Nambu-Goto matching conditions
Georgios Kofinas, Emmanuel N. Saridakis, Jun-Qing Xia
We investigate the cosmological implications of the recently constructed 5-dimensional braneworld cosmology with gravitating Nambu-Goto matching conditions. Inserting both matter a…
