Quantum theory of scalar field in isotropic world
K. A. Bronnikov, E. A. Tagirov
Fock representations are constructed for a free scalar field in the closed and quasi-Euclidean isotropic cosmological models. Invariance of their cyclic vector (vacuum) under isome…
Conformal continuations and wormhole instability in scalar-tensor gravity
K. A. Bronnikov, S. V. Grinyok
We study the stability of static, spherically symmetric, traversable wormholes existing due to conformal continuations in a class of scalar-tensor theories with zero scalar field p…
Nonsingular multidimensional cosmologies with Lobachevsky spatial sections
K. A. Bronnikov
Examples of nonsingular cosmological models are presented on the basis of exact solutions to multidimensional gravity equations. These examples involve pure imaginary scalar fields…
A general thick brane supported by a scalar field
Kirill A. Bronnikov, Boris E. Meierovich
A thick Z_2-symmetric domain wall supported by a scalar field with an arbitrary potential V(ϕ) in 5D general relativity is considered as a candidate brane world. We show that, unde…
Magneto-dilatonic Bianchi-I cosmology: isotropization and singularity problems
K. A. Bronnikov, E. N. Chudaeva, G. N. Shikin
We study the evolution of Bianchi-I space-times filled with a global unidirectional electromagnetic field interacting with a massless scalar dilatonic field according to t…
