Variations of and from nonlinear multidimensional gravity
K. A. Bronnikov, M. V. Skvortsova
To explain the recently reported large-scale spatial variations of the fine structure constant , we apply some models of curvature-nonlinear multidimensional gravity. Under the…
Example of a stable wormhole in general relativity
K. A. Bronnikov, L. N. Lipatova, I. D. Novikov +1
We study a static, spherically symmetric wormhole model whose metric coincides with that of the so-called Ellis wormhole but the material source of gravity consists of a perfect fl…
Dilaton gravity, (quasi-) black holes, and scalar charge
K. A. Bronnikov, J. C. Fabris, R. Silveira +1
We consider static electrically charged dust configurations in the framework of Einstein-Maxwell-dilaton gravity with the interaction term P(χ) F_{mn} F^{mn} in the Lagrangian, whe…
Rotating cylindrical wormholes
Kirill A. Bronnikov, Vladimir G. Krechet, José P. S. Lemos
We consider stationary, cylindrically symmetric configurations in general relativity and formulate necessary conditions for the existence of rotating cylindrical wormholes. It is s…
Nonlinear multidimensional gravity and the Australian dipole
K. A. Bronnikov, V. N. Melnikov, S. G. Rubin +1
The existing observational data on possible variations of fundamental physical constants (FPC) confirm more or less confidently only a variability of the fine structure constant $α…
