Cosmological solutions in F(T) gravity with the presence of spinor fields
Ratbay Myrzakulov, Diego Saez-Gomez, Petr Tsyba
The presence of spinor fields is considered in the framework of some extensions of teleparallel gravity, where the Weitzenböck connection is assumed. Some well known models as the…
Periodic Cosmological Evolutions of Equation of State for Dark Energy
Kazuharu Bamba, Ujjal Debnath, Kuralay Yesmakhanova +3
We demonstrate two periodic or quasi-periodic generalizations of the Chaplygin gas (CG) type models to explain the origins of dark energy as well as dark matter by using the Weiers…
Reconstruction of f-essence and fermionic Chaplygin gas models of dark energy
P. Tsyba, K. Yerzhanov, K. Esmakhanova +3
Recently, it was proposed a new fermionic model of dark energy, the so-called f-essence. In this work, we explicitly reconstruct the different f-essence models. In particular, thes…
Accelerated expansion of the Universe driven by G-essence
K. K. Yerzhanov, P. Yu. Tsyba, Sh. R. Myrzakul +2
In the present work we analyze the g-essence model for the particular Lagrangian: . The g-essence models were proposed recently as an alternative and as…
G-essence with Yukawa Interactions
I. Kulnazarov, K. Yerzhanov, O. Razina +3
We study the g-essence model with Yukawa interactions between a scalar field and a Dirac field . For the homogeneous, isotropic and flat Friedmann-Robertson-Walker universe…
Pure kinetic k-essence as the cosmic speed-up
P. Y. Tsyba, I. I. Kulnazarov, K. K. Yerzhanov +1
In this paper, we consider three types of k-essence. These k-essence models were presented in the parametric forms. The exact analytical solutions of the corresponding equations of…
