Barrow agegraphic dark energy
Umesh Kumar Sharma, Gunjan Varshney, Vipin Chandra Dubey
In this work, we propose a new dark energy model by applying the Barrow entropy and the holographic principle, with a time scale as IR cut off. Analysing the conformal time as well…
Transitioning Universe with hybrid scalar field in Bianchi I space-time
Anil Kumar Yadav, A. M. Alshehri, Nafis Ahmad +2
In this paper we investigate a Bianchi type I transitioning Universe in Brans-Dicke theory. To get an explicit solution of the field equations, we assume scalar field as $ϕ= ϕ_{0}\…
Compatibility between the scalar field models of tachyon, -essence and quintessence in gravity
Vinod Kumar Bhardwaj, Anirudh Pradhan, Archana Dixit
We investigate the behavior of the scalar field in gravity (Harko et al., Phys. Rev. D 84, 024020, 2011) inside the structure of a flat FRW cosmological model, where $R…
RHDE models in FRW Universe with two IR cut-offs with redshift parametrization
Archana Dixit, Vinod Kumar Bhardwaj, Anirudh Pradhan
In this manuscript, we have researched the cosmic expansion phenomenon in flat FRW Universe through the interaction of the recently proposed Rnyi holographic dark energy…
Evaporation of dynamical horizon with the Hawking temparature in the {\bf K-}essence emergent Vaidya spacetime
Bivash Majumder, Saibal Ray, Goutam Manna
In the {\bf K-}essence Vaidya Schwarzschild spacetime, we apply the dynamical horizon equation to measure the mass-loss due to Hawking radiation and the tunneling formalism (Hamilt…
Color-flavor locked quark stars in energy-momentum squared gravity
Ksh. Newton Singh, Ayan Banerjee, S. K. Maurya +2
Several attempts have been made in the past decades to search for the true ground state of the dense matter at sufficiently large densities and low temperatures via compact astroph…
