Co-existence of alternative Generalized Chaplygin Gas and other Dark Energies in the Framework of Fractal Universe
Mahasweta Biswas, Rikpratik Sengupta, Ujjal Debnath
We have explored the possibility of the co-existence of two forms of dark energy in the form of an alternative Generalized Chaplygin Gas (GCG) along with a scalar field of field th…
Holographic application in cosmology: Thermodynamics of the Van der Waals cosmic fluid
Mahasweta Biswas, Sayani Maity, Ujjal Debnath
This paper is devoted to investigate the thermodynamic stability of a generic cosmological fluid known as Van der Waals fluid in the context of flat FRW universe. It is treated as…
Generalized Ghost Dark Energy in DGP Model
Mahasweta Biswas, Shounak Ghosh, Ujjal Debnath
In 2000, Giorgi Dvali, Gregory Gabadadze and Massimo Porrati (Dvali et al. 2000) was proposed a new braneworld model named as DGP model, having two branches with and $(ε=-…
Study of QCD generalized ghost dark energy in FRW universe
Mahasweta Biswas, Ujjal Debnath, Shounak Ghosh +1
A phenomenological generalized ghost dark energy model has been studied under the framework of FRW universe. In ghost dark energy model the energy density depends linearly on Hubbl…
