On horizons and wormholes in k-essence theories
K. A. Bronnikov, J. C. Fabris, D. C. Rodrigues
We study the properties of possible static, spherically symmetric configurations in k-essence theories with the Lagrangian functions of the form , . A…
Visible, invisible and trapped ghosts as sources of wormholes and black universes
S. V. Bolokhov, K. A. Bronnikov, P. A. Korolyov +1
We construct explicit examples of globally regular static, spherically symmetric solutions in general relativity with scalar and electromagnetic fields, describing traversable worm…
Rotating cylindrical wormholes: a no-go theorem
K. A. Bronnikov
The existing solutions to the Einstein equations describing rotating cylindrical wormholes are not asymptotically flat and therefore cannot describe wormhole entrances as local obj…
Rotating cylindrical wormholes and energy conditions
K. A. Bronnikov, V. G. Krechet
We seek wormholes among rotating cylindrically symmetric configurations in general relativity. Exact wormhole solutions are presented with such sources of gravity as a massless sca…
Wormholes without exotic matter in Einstein-Cartan theory
K. A. Bronnikov, A. M. Galiakhmetov
We study the possible existence of static traversable wormholes without invoking exotic matter in the framework of the Einstein--Cartan theory. A family of exact static, sphericall…
Quasi-black holes: general features and purely field configurations
K. A. Bronnikov, O. B. Zaslavskii
Objects that are on the threshold of forming the horizon but never collapse are called quasi-black holes (QBHs). We discuss the properties of the general spherically symmetric QBH…
On supersymmetric M-brane configurations with R^{1,1}_{*}/Z_2 submanifold
V. D. Ivashchuk
We obtain new examples of partially supersymmetric M-brane solutions defined on products of Ricci-flat manifolds, which contain two-dimensional Lorentzian submanifold R^{1,1}_{*}/Z…
Dilatonic dyon black hole solutions
M. E. Abishev, K. A. Boshkayev, V. D. Dzhunushaliev +1
Dilatonic black hole dyon solutions with arbitrary dilatonic coupling constant and canonical sign for scalar field kynetic term are considered. These s…
Magnetic wormholes and black universes with invisible ghosts
K. A. Bronnikov, P. A. Korolyov
We construct explicit examples of globally regular static, spherically symmetric solutions in general relativity with scalar and electromagnetic fields describing traversable wormh…
On exponential cosmological type solutions in the model with Gauss-Bonnet term and variation of gravitational constant
V. D. Ivashchuk, A. A. Kobtsev
A D-dimensional gravitational model with Gauss-Bonnet term is considered. When ansatz with diagonal cosmological type metrics is adopted, we find solutions with exponential depende…
