We review the paradigm of holographic dark energy (HDE), which arises from a theoretical
attempt of applying the holographic principle (HP) to the dark energy (DE) problem. Making …

There is strong evidence that the area of any surface limits the information content of
adjacent spacetime regions, at 1.4× 10 69 bits per square meter. This article reviews the …

We formulate Barrow holographic dark energy, by applying the usual holographic principle
at a cosmological framework, but using the Barrow entropy instead of the standard …

Employing the modified entropy–area relation suggested by Tsallis and Cirto [1], and the
holographic hypothesis, a new holographic dark energy (HDE) model is proposed …

Recently, the Rényi and Tsallis generalized entropies have extensively been used in order
to study various cosmological and gravitational setups. Here, using a special type of …

We use observational data from Supernovae (SNIa) Pantheon sample, as well as from direct
measurements of the Hubble parameter from the cosmic chronometers (CC) sample, in …

A model for holographic dark energy is proposed, following the idea that the short distance
cut-off is related to the infrared cut-off. We assume that the infrared cut-off relevant to the …

We review the paradigm of quintom cosmology. This scenario is motivated by the
observational indications that the equation-of-state of dark energy across the cosmological …

In order to apply holography and entropy relations to the whole universe, which is a
gravitational and thus nonextensive system, for consistency one should use the generalized …

We construct a holographic dark energy scenario based on Kaniadakis entropy, which is a
generalization of Boltzmann-Gibbs entropy that arises from relativistic statistical theory and …
