Reconstruction of f(G) Gravity from an Interacting Viscous Generalized QCD Ghost Dark Energy Model: Cosmology and Thermodynamics: Cosmology and Thermodynamics
Zhanar Umurzakhova, Aziza Altaibayeva, Ulbossyn Ualikhanova +1
In this work, we investigate an interacting viscous generalized QCD ghost dark energy model in the framework of reconstructed gravity proposed in Phys.\ Lett.\ B 631, 1--6 (…
A Combined Barrow Entropy and QCD Ghost Mechanism for Late-Time Cosmic Acceleration
Aziza Altaibayeva, Ulbossyn Ualikhanova, Zhanar Umurzakhova +1
We investigate a unified dark-energy scenario based on the combined effects of Barrow entropy corrections and the QCD ghost mechanism, referred to as the BH--QCDGDE model. The dark…
Initial conditions of pre-inflation with Hilltop potential in loop quantum cosmology
M. Shahalam, Kuralay Yesmakhanova, Zhanar Umurzakhova
In this paper, we investigate the dynamics of pre-inflation with Hilltop potential in the framework of loop quantum cosmology. The initial conditions of inflaton field at the quant…
Generalized Heisenberg Ferromagnet type Equation and Modified Camassa-Holm Equation: Geometric Formulation, Soliton Solutions and Equivalence
Zhanar Umurzakhova, Tolkynay Myrzakul, Kuralay Yesmakhanova +3
We study the integrability and equivalence of a generalized Heisenberg ferromagnet-type equation (GHFE). The different forms of this equation as well as its reduction are presented…
