Electroweak multi-monopoles
Romain Gervalle, Mikhail S. Volkov
We construct the multi-charge generalizations for the electroweak magnetic monopole solution of Cho and Maison within a wide range of values of the magnetic charge. We use the same…
Electroweak monopoles and their stability
Romain Gervalle, Mikhail S. Volkov
We apply a generalized field ansatz to describe the spherically symmetric sector of classical solutions of the electroweak theory. This sector contains Abelian magnetic monopoles l…
Asymptotically flat hairy black holes in massive bigravity
Romain Gervalle, Mikhail S. Volkov
We study asymptotically flat black holes with massive graviton hair within the ghost-free bigravity theory. There have been contradictory statements in the literature about their e…
Anisotropy screening in Horndeski cosmologies
Alexei A. Starobinsky, Sergey S. Sushkov, Mikhail S. Volkov
We consider anisotropic cosmologies in a particular shift-symmetric Horndeski theory containing the coupling, where is the Einstein tensor.…
A metric-affine version of the Horndeski theory
Thomas Helpin, Mikhail S. Volkov
We study the metric-affine versions of scalar-tensor theories whose connection enters the action only algebraically. We show that the connection can be integrated out in this case,…
Massive spin-2 field in arbitrary spacetimes -- the detailed derivation
Charles Mazuet, Mikhail S. Volkov
We present the consistent theory of a free massive spin-2 field with 5 degrees of freedom propagating in spacetimes with an arbitrary geometry. We obtain this theory via linearizin…
Massive gravitons in arbitrary spacetimes
Charles Mazuet, Mikhail S. Volkov
We present two different versions of the consistent theory of massive gravitons in arbitrary spacetimes which are simple enough for practical applications. The theory is described…
Zero mass limit of Kerr spacetime is a wormhole
Gary W. Gibbons, Mikhail S. Volkov
We show that, contrary to what is usually claimed in the literature, the zero mass limit of Kerr spacetime is not flat Minkowski space but a spacetime whose geometry is only locall…
Weyl metrics and wormholes
Gary W. Gibbons, Mikhail S. Volkov
We study solutions obtained via applying dualities and complexifications to the vacuum Weyl metrics generated by massive rods and by point masses. Rescaling them and extending to c…
Ring wormholes via duality rotations
Gary W. Gibbons, Mikhail S. Volkov
We apply duality rotations and complex transformations to the Schwarzschild metric to obtain wormhole geometries with two asymptotically flat regions connected by a throat. In the…
The screening Horndeski cosmologies
Alexei A. Starobinsky, Sergey V. Sushkov, Mikhail S. Volkov
We present a systematic analysis of homogeneous and isotropic cosmologies in a particular Horndeski model with Galileon shift symmetry, containing also a -term and a matter. The…
Giant wormholes in ghost-free bigravity theory
Sergey V. Sushkov, Mikhail S. Volkov
We study Lorentzian wormholes in the ghost-free bigravity theory described by two metrics, g and f. Wormholes can exist if only the null energy condition is violated, which happens…
De Sitter vacua in ghost-free massive gravity theory
Charles Mazuet, Mikhail S. Volkov
We present a simple procedure to obtain all de Sitter solutions in the ghost-free massive gravity theory by using the Gordon ansatz. For these solutions the physical metric can be…

This is a brief survey of the known black hole solutions in the theories of ghost-free bigravity and massive gravity. Various black holes exist in these theories, in particular tho…

The detailed calculations of the energy in the ghost-free massive gravity theory is presented. The energy is defined in the standard way within the canonical approach, but to evalu…
Stability of Minkowski space in ghost-free massive gravity theory
Mikhail S. Volkov
The energy in the ghost-free massive gravity theory is calculated via explicitly resolving the initial value constraints for spherically symmetric deformations of flat space. It tu…
