Multidimensional world, inflation and modern acceleration
K. A. Bronnikov, S. G. Rubin, I. V. Svadkovsky
Starting from pure multidimensional gravity with curvature-nonlinear terms but no matter fields in the initial action, we obtain a cosmological model with two effective scalar fiel…
Possible black universes in a brane world
K. A. Bronnikov, E. V. Donskoy
A black universe is a nonsingular black hole where, beyond the horizon, there is an expanding, asymptotically isotropic universe. Such spherically symmetric configurations have bee…
Horizons in matter: black hole hair vs. Null Big Bang
K. A. Bronnikov, O. B. Zaslavskii
It is shown that only particular kinds of matter (in terms of the "radial" pressure to density ratio ) can coexist with Killing horizons in black-hole or cosmological space-time…
Wormholes supported by chiral fields
K. A. Bronnikov, S. V. Chervon, S. V. Sushkov
We consider static, spherically symmetric solutions of general relativity with a nonlinear sigma model (NSM) as a source, i.e., a set of scalar fields (so-called…
General static black holes in matter
K. A. Bronnikov, O. B. Zaslavskii
For arbitrary static space-times, it is shown that an equilibrium between a Killing horizon and matter is only possible for some discrete values of the parameter , where…
Once again on thin-shell wormholes in scalar-tensor gravity
Kirill A. Bronnikov, Alexei A. Starobinsky
It is proved that all thin-shell wormholes built from two identical regions of vacuum static, spherically symmetric space-times have a negative shell surface energy density in any…
Cylindrical wormholes
Kirill A. Bronnikov, José P. S. Lemos
It is shown that the existence of static, cylindrically symmetric wormholes does not require violation of the weak or null energy conditions near the throat, and cylindrically symm…
