Generalized α-Attractor Models from Elementary Hyperbolic Surfaces [PDF]

open access: yesAdvances in Mathematical Physics, 2018
We consider generalized α-attractor models whose scalar potentials are globally well-behaved and whose scalar manifolds are elementary hyperbolic surfaces.

Generalized two-field α-attractor models from the hyperbolic triply-punctured sphere [PDF]

open access: yesNuclear Physics B, 2018
We study generalized two-field α-attractor models whose rescaled scalar manifold is the triply-punctured sphere endowed with its complete hyperbolic metric, whose underlying complex manifold is the modular curve Y(2). Using an explicit embedding into the

Sculpting the Standard Model from low-scale gauge-Higgs-matter E8 grand unification in ten dimensions

open access: yesNuclear Physics B, 2023
The construction and general implications of a model with complete supersymmetric unification of the Standard Model matter content, interactions and families' replication into a single E8 gauge superfield in ten dimensions is presented.

Scalar-tensor theory with EGB term from Einstein Chern-Simons gravity

open access: yesNuclear Physics B, 2023
It is shown that the compactification á la Randall-Sundrum of the so-called, five-dimensional Einstein-Chern-Simons action gravity leads to an action for a four-dimensional scalar-tensor gravity that includes a Gauss-Bonnet term, which belongs to a ...

Dynamics of a Cosmological Model in f(R,T) Gravity: I. On Invariant Planes

open access: yesUniverse, 2022
Under the background of perfect fluid and flat Friedmann–Lemaître–Robertson–Walker (FLRW) space-time, this paper mainly describes the dynamics of the cosmological model constructed in f(R,T) gravity on three invariant planes, by using the singularity ...

Dynamical Analysis and Periodic Solution of a Chaotic System with Coexisting Attractors

open access: yesComplexity, 2021
Chaotic attractors with no equilibria, with an unstable node, and with stable node-focus are presented in this paper. The conservative solutions are investigated by the semianalytical and seminumerical method.

Derivation of a Unified Theory from the Holographic Principle

open access: yesReports in Advances of Physical Sciences, 2023
Holographic principle and the related self-similarity symmetry are observed widely in nature. Research in black hole, string theory and quantum theory of gravity suggests that holographic principle can be an important symmetry for solving challenging ...

Dynamics of a Cosmological Model in f(R,T) Gravity: II. In Three-Dimensional Space

open access: yesUniverse, 2023
Based on the results discussed on the invariant planes in the known literature [Universe 2022, 8, 365] for the flat FLRW space-time universe model with ideal fluid under the gravity of f(R,T)=ξRα+ζ−T, this paper continues to describe the global dynamics ...

Single extra dimension from κ-Poincaré and gauge invariance

open access: yesJournal of High Energy Physics, 2021
We show that κ-Poincaré invariant gauge theories on κ-Minkowski space with physically acceptable commutative (low energy) limit must be 5-d. The gauge invariance requirement of the action fixes the dimension of the κ-Minkowski space to d = 5 and selects ...

On generic homogeneous vector fields

open access: yesИзвестия высших учебных заведений. Поволжский регион: Физико-математические науки, 2022
Background. The study of dynamical systems with symmetry is of both theoretical and applied interest. Phase portraits of dynamical systems defined by homogeneous vector fields are invariant with respect to the phase space dilation group.
