Magnetic fields in mixed neutron-star-plus-wormhole systems
Ascar Aringazin, Vladimir Dzhunushaliev, Vladimir Folomeev +2
We consider mixed configurations consisting of a wormhole filled by a strongly magnetized isotropic or anisotropic neutron fluid. The nontrivial topology of the spacetime is allowe…
Boson Stars with Nontrivial Topology
Vladimir Dzhunushaliev, Vladimir Folomeev, Christian Hoffmann +2
We construct boson star solutions in the presence of a phantom field, allowing for a nontrivial topology of the solutions. The wormholes residing at the core of the configurations…
Propagation of gravitational waves in the nonperturbative spinor vacuum
Vladimir Dzhunushaliev, Vladimir Folomeev
The propagation of gravitational waves on the background of a nonperturbative vacuum of a spinor field is considered. It is shown that there are several distinctive features in com…
Modified gravity from the quantum part of the metric
Vladimir Dzhunushaliev, Vladimir Folomeev, Burkhard Kleihaus +1
It is shown that if a metric in quantum gravity can be decomposed as a sum of classical and quantum parts then Einstein quantum gravity looks approximately like modified gravity wi…
Hiding a neutron star inside a wormhole
Vladimir Dzhunushaliev, Vladimir Folomeev, Burkhard Kleihaus +1
We consider neutron-star-plus-wormhole configurations supported by a massless ghost scalar field. The neutron fluid is modeled by an anisotropic equation of state. When the central…
