Nonlinear electrodynamics, regular black holes and wormholes
K. A. Bronnikov
We consider spherically symmetric configurations in general relativity, supported by nonlinear electromagnetic fields with gauge-invariant Lagrangians depending on the single invar…
Inhomogeneous compact extra dimensions
K. A. Bronnikov, R. I. Budaev, A. V. Grobov +2
We show that an inhomogeneous compact extra space possesses two necessary features --- their existence does not contradict the observable value of the cosmological constant i…
Dyonic configurations in nonlinear electrodynamics coupled to general relativity
K. A. Bronnikov
We consider static, spherically symmetric configurations in general relativity, supported by nonlinear electromagnetic fields with gauge-invariant Lagrangians depending on the sing…
Wormholes with fluid sources: A no-go theorem and new examples
K. A. Bronnikov, K. A. Baleevskikh, M. V. Skvortsova
For static, spherically symmetric space-times in general relativity (GR), a no-go theorem is proved: it excludes the existence of wormholes with flat and/or AdS asymptotic regions…
On wormholes with long throats and the stability problem
K. A. Bronnikov, P. A. Korolyov
We construct explicit examples of globally regular static, spherically symmetric solutions of general relativity with a phantom scalar field as the source of gravity, describing tr…
Duality between k-essence and Rastall gravity
Kirill A. Bronnikov, Julio C. Fabris, Oliver F. Piattella +2
The k-essence theory with a power-law function of and Rastall's non-conservative theory of gravity with a scalar field are shown to have the same solutions for the…
