  • Exact wormhole solutions with nonminimal kinetic coupling 
    Korolev R.; Sushkov S. (2014)
    © 2014 American Physical Society. We consider static spherically symmetric solutions in the scalar-tensor theory of gravity with a scalar field possessing the nonminimal kinetic coupling to the curvature. The Lagrangian ...
  • General constraints on horndeski wormhole throats 
    Korolev R.; Lobo F.S.N.; Sushkov S.V. (2020)
    © 2020 American Physical Society In this work, we consider the full Horndeski Lagrangian applied to wormhole geometries and present the full gravitational field equations. We analyze the general constraints imposed by the ...
  • Kinetic gravity braiding wormhole geometries 
    Korolev R.; Lobo F.S.N.; Sushkov S.V. (2020)
    © 2020 American Physical Society. An interesting class of scalar-tensor models, denoted by kinetic gravity braiding (KGB), has recently been proposed. These models contain interactions of the second derivatives of the ...
  • Scalar wormholes with nonminimal derivative coupling 
    Sushkov S.; Korolev R. (2012)
    We consider static spherically symmetric wormhole configurations in a gravitational theory of a scalar field with a potential V() and nonminimal derivative coupling to the curvature described by the term (εg μν + κG μν)φ ...
