  • Anisotropic deformations of spatially open cosmology in massive gravity theory 
    Mazuet C.; Mukohyama S.; Volkov M. (2017)
    © 2017 IOP Publishing Ltd and Sissa Medialab srl .We combine analytical and numerical methods to study anisotropic deformations of the spatially open homogeneous and isotropic cosmology in the ghost free massive gravity ...
  • De Sitter vacua in ghost-free massive gravity theory 
    Mazuet C.; Volkov M. (2015)
    © 2015. We present a simple procedure to obtain a large class of different versions of the de Sitter solution in the ghost-free massive gravity theory via applying the Gordon ansatz. For these solutions the physical metric ...
  • Energy in ghost-free massive gravity theory 
    Volkov M. (2014)
    © 2014 American Physical Society. The detailed calculations of the energy in the ghost-free massive gravity theory are presented. The energy is defined in the standard way within the canonical approach, but to evaluate it ...
  • Giant wormholes in ghost-free bigravity theory 
    Sushkov S.; Volkov M. (2015)
    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 naturally in the bigravity theory since ...
  • Hairy black holes in theories with massive gravitons 
    Volkov M. (2015)
    © Springer International Publishing Switzerland 2015. 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 ...
  • Massive gravitons in arbitrary spacetimes 
    Mazuet C.; Volkov M. (2017)
    © 2017 American Physical Society. 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 by a ...
  • Massive spin-2 field in arbitrary spacetimes - The detailed derivation 
    Mazuet C.; Volkov M. (2018)
    © 2018 IOP Publishing Ltd and Sissa Medialab. 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 ...
  • Ring wormholes via duality rotations 
    Gibbons G.; Volkov M. (2016)
    © 2016 The AuthorsWe 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 simplest case these are ...
  • Stability of Minkowski space in ghost-free massive gravity theory 
    Volkov M. (2014)
    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 turns out that the energy is positive in ...
  • The Ogievetsky-Polubarinov massive gravity and the benign Boulware-Deser mode 
    Mukohyama S.; Volkov M. (2018)
    © 2018 IOP Publishing Ltd and Sissa Medialab. We present our analysis of the theory constructed in 1965 by Ogievetsky and Polubarinov (OP) - the first ever theory of interacting massive gravitons. Its mass term is adjusted ...
  • The screening Horndeski cosmologies 
    Starobinsky A.; Sushkov S.; Volkov M. (2016)
    We present a systematic analysis of homogeneous and isotropic cosmologies in a particular Horndeski model with Galileon shift symmetry, containing also a Λ-term and a matter. The model, sometimes called Fab Five, admits a ...
  • Thermal lens investigation in EuF<inf>2.11</inf>, PrF<inf>3</inf>, and Na<inf>0.38</inf>Ho<inf>0.62</inf>F<inf>2.24</inf> crystals for magnetooptical applications 
    Starobor A.; Mironov E.; Volkov M.; Karimov D.; Ivanov I.; Lovchev A.; Naumov A.; Semashko V.; Palashov O. (2019)
    © 2019 Elsevier B.V. Thermal lens, absorption coefficient for 1076 nm radiation and spectral dependence of the Verdet constant were measured in PrF3, EuF2.11 and Na0.38Ho0.62F2.24 crystals for magneto-optical applications. ...
  • Weyl metrics and wormholes 
    Gibbons G.; Volkov M. (2017)
    © 2017 IOP Publishing Ltd and Sissa Medialab srl. 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 ...
  • Zero mass limit of Kerr spacetime is a wormhole 
    Gibbons G.; Volkov M. (2017)
    © 2017 American Physical Society. 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 locally flat. ...
