Black holes in f(R) theory of gravity with compact extra dimensions
Arkady Popov, Sergey Rubin
We study static, spherically symmetric solutions in gravity within a -dimensional spacetime, where the extra dimensions form a compact -sphere of constant radius…
Formation and evolution of a 2-brane structure in multidimensional gravity
Kirill A. Bronnikov, Arkady A. Popov, Sergey G. Rubin
It has been previously shown that multidimensional gravity {can lead} to a two-brane structure. In this paper, we analyze such a model with a spatially flat 4D de Sitter (dS…
Spontaneous branes formation
Arkadiy A. Popov, Sergey G. Rubin
This paper presents a study of brane formation in six-dimensional space. There is no a priori assumption of the brane(s) existence. However, the analysis of the generalized Einstei…
Primordial Black Holes from Spatially Varying Cosmological Constant Induced by Field Fluctuations in Extra Dimensions
Arkady A. Popov, Sergey G. Rubin, Alexander S. Sakharov
The origin and evolution of supermassive black holes (SMBHs) in our universe have sparked controversy. In this study, we explore the hypothesis that some of these black holes may h…
