Bianchi IX dynamics with a phantom field
Adel Awad, Dmitry Chirkov, Alexey Golovnev +1
We consider Bianchi IX dynamics of a Universe filled with a massless phantom field. Such an exotic matter source enables regimes impossible in vacuum or with a standard scalar fiel…
Spontaneous symmetry breaking as a result of extra dimensions compactification
Dmitry Chirkov, Alex Giacomini, Alexey Toporensky +1
We consider dynamics of a scalar field in compactification scenario of Einstein-Gauss-Bonnet cosmology. It is shown that if the field is non-minimally coupled to curvature, its asy…
Stability analysis of compactification in 3-d order Lovelock gravity
Dmitry Chirkov, Alexey Toporensky
It is known that spatial curvature can stabilize extra dimensions in Lovelock gravity. In the present paper we study stability of the stabilization solutions in 3-d order Lovelock…
Some aspects of the cosmological dynamics in Einstein-Gauss-Bonnet gravity
Dmitry Chirkov, Sergey A. Pavluchenko
We study some aspects of dynamical compactification scenario where stabilisation of extra dimensions occurs due to presence the Gauss-Bonnet term and non-zero spatial curvature. In…
Cosmological solutions in Einstein-Gauss-Bonnet gravity with static curved extra dimensions
Dmitry Chirkov, Alex Giacomini, Sergey A. Pavluchenko +1
In this paper we perform systematic investigation of all possible solutions with static compact extra dimensions and expanding three-dimensional subspace (``our Universe''). Unlike…
Anisotropic cosmological dynamics in Einstein-Gauss-Bonnet gravity: an example of dynamical compactification in 7+1 dimensions
Dmitry Chirkov, Alex Giacomini, Alexey Toporensky
We consider a particular example of dynamical compactification of an anisotropic 7+1 dimensional Universe in Einstein - Gauss - Bonnet gravity. Starting from rather general totally…
