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…
Accelerating cosmology in F(T) gravity with scalar field
K. K. Yerzhanov, Sh. R. Myrzakul, I. I. Kulnazarov +1
This work deals with gravity models driven by real scalar fields with usual and phantom dynamics. We illustrate the results with examples of current interest, and we find so…
