Tsallis holographic dark energy in Bianchi-I Universe using hybrid expansion law with k-essence

Bianchi type-III Tsallis holographic dark energy model in Saez–Ballester theory of gravitation

“…They have concluded that the EoS parameter indicates phantom phase while the deceleration parameter demonstrates accelerated cosmic epoch for both conserved as well as non-conserved energy-momentum tensor. Dubey et al [53,65] have studied Bianchi type-I and I I I THDE models. In both the models, the EoS parameter approaches to CDM model in future.…”

“…Here, we would like to study the difference between our work and the other THDE models studied in literature [43][44][45][46][47][48][49][50][51][52][53]. Zadeh et al [43] have explored the effects of various IR cutoffs on the properties of THDE model.…”

“…Zadeh et al [51] explained the cosmic evolution of Bianchi type-I THDE model with sign-changeable interaction between DM and DE with various IR cutoffs. Dubey et al [52] have discussed THDE models with Hubble horizon as IR cutoff in axially symmetric Biachi type-I space-time whereas, Dubey et al [53] have studied THDE in Bianchi type-I Universe using hybrid expansion law with k-essence. THDE model with anisotropic background and in the framework of Saez-Ballester scalar-tensor theory of gravitation has not been, so far, studied in literature.…”

“…Neither in [ 2 ] nor in [ 3 ] is a specific position taken for black holes being or physical objects, or even (multi)fractal objects with nonintenger d (which, to the best of our knowledge, may not be excluded). At the present stage, it seems appropriate to analyze this nontrivial and delicate issue within the specialized realm of cosmological and black-hole physics [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 ]. However, it is seemingly undeniable that the sort of perplexity expressed in [ 49 , …”

Black Hole Entropy: A Closer Look

“…Nowadays many studies (see, for instance, [ 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 ]) address entropic issues based on nonadditive entropic functionals such as , or (see also [ 61 ], where possible alternative interpretations of the entropic forms have been advanced). They focus on black holes, cosmological issues (e.g., dark energy), and various kinds of quantum-entangled systems.…”
