(Lovelock) inflation: explaining the ACT data and equivalence to Higgs-Gauss-Bonnet inflation
Andrea Addazi, Yermek Aldabergenov, Daulet Berkimbayev +1
We revisit the Starobinsky model of inflation in light of recent data from the Atacama Cosmology Telescope (ACT), which indicates a potential preference for a slightly larger scala…
Domain Wall formation from spontaneous symmetry breaking/restoration in Scalar-Einstein-Gauss-Bonnet theory
Maxim Krasnov, Daulet Berkimbayev, Andrea Addazi +2
This study offers a detailed analysis of domain wall formation and its cosmological consequences in Einstein-Gauss-Bonnet gravity coupled to a scalar field. A central aspect of the…
Energy transfer between the sources in gravitational decoupling
Daulet Berkimbayev
A straightforward and fully analytic approach is introduced to examine how polytropic fluids influence arbitrary gravitational sources in static, spherically symmetric spacetimes.…
Discrete Action, Graph Evolution, and the Hierarchy of Symmetries: A Rigorous Construction of Temporal Layers
Medeu Abishev, Daulet Berkimbayev
Postulating a minimal discrete quantum of action and a simple rule for the growth of an oriented graph, we construct a strict hierarchy of temporal layers with disc…
Effects of matter with anisotropic pressure on the Fan-Wang regular black hole shadows
Yergali Kurmanov, Orlando Luongo, Daulet Berkimbayev +4
We here investigate the consequences of an exotic fluid, exhibiting negative radial and tangential pressures, \emph{de facto} violating the Zel'dovich limit, on a regular solution…
Gauss-Bonnet-induced symmetry breaking/restoration during inflation
Yermek Aldabergenov, Daulet Berkimbayev
We propose a mechanism of symmetry breaking or restoration that can occur in the middle of inflation due to the coupling of the Gauss-Bonnet term to a charged scalar. The Gauss-Bon…
