A Non-Linear Type Equation of State and Cosmic Fluid Dynamics
Shouvik Sadhukhan, Alokananda Kar, Surajit Chattopadhyay
In this chapter we have introduced a special type of non-linear equation of state to discuss the cosmological evolution mechanism. The new equation of state is a four parameters mo…
Multiple fluid theory of cosmic evolution and its thermodynamic analysis
Shouvik Sadhukhan, Alokananda Kar, Surajit Chattopadhyay
In this paper we have discussed the modified gravity and scalar field DE model specifically DBI essence model with the analysis of thermodynamics during cosmological evolution. We…
Energy conditions for Inhomogeneous EOS and its Thermodynamics analysis with the resolution on finite time future singularity problems
Alokananda Kar, Shouvik Sadhukhan, Surajit Chattopadhay
In this paper we study two different cases of inhomogeneous EOS of the form p_d = ω(t)ρ_d+w_1 f(H, t) . We derive the energy density of dark fluid and dark matter component for bot…
Thermodynamics and energy condition analysis for Van-Der-Waals EOS without viscous cosmology
Alokananda Kar, Shouvik Sadhukhan, Surajit Chattopadhyay
In this paper we have studied Van-Der-Waals fluid system with the generalized EOS as as discussed in the recent works of Kremer, G.M [1, 4], Vardiashvili, G [2], Jantsch, R.C [3],…
Modified Holographic energy density driven inflation and some cosmological outcomes
Gargee Chakraborty, Surajit Chattopadhyay
Motivated by the work of Nojiri et al. (2019) [S. Nojiri, S. D. Odintsov and E. N. Saridakis, Holographic inflation, Phys. Lett. B 797 (2019) 134829], the present study reports a m…
Cosmology of a generalised version of holographic dark energy in presence of bulk viscosity and its inflationary dynamics through slow roll parameters
Gargee Chakraborty, Surajit Chattopadhyay
The present study reports a reconstruction scheme of a Dark Energy (DE) model with higher order derivative of Hubble parameter, which is a particular case of Nojiri-Odintsov hologr…
