Modeling holographic dark energy with particle and future horizons
Nuclear Physics B, 2020 In this work we explore some cosmological properties coming from the particle and future horizons when are considered as candidates to model the dark energy sector within a holographic context in a flat Friedmann-Lemaitre-Robertson-Walker universe; we ...

Dynamics and epicyclic motions of particles around the Schwarzschild–de Sitter black hole in perfect fluid dark matter [PDF]
European Physical Journal C: Particles and Fields, 2021 In this paper, we investigate circular orbits for test particles around the Schwarzschild–de Sitter (dS) black hole surrounded by perfect fluid dark matter.

Instability and phase transitions of a rotating black hole in the presence of perfect fluid dark matter [PDF]
European Physical Journal C: Particles and Fields, 2020 In this paper, we study the thermodynamic features of a rotating black hole surrounded by perfect fluid dark matter. We analyze the critical behavior of the black hole by considering the known relationship between pressure and cosmological constant.

The logotropic dark fluid: Observational and thermodynamic constraints [PDF]
International Journal of Modern Physics D, 2020 We have considered a spatially flat, homogeneous and isotropic FLRW Universe filled with a single fluid, known as logotropic dark fluid (LDF), whose pressure evolves through a logarithmic equation of state.

Testing the weak cosmic censorship conjecture for a Reissner–Nordström–de Sitter black hole surrounded by perfect fluid dark matter [PDF]
European Physical Journal C: Particles and Fields, 2021 In this paper, we test the weak cosmic censorship conjecture (WCCC) for the Reissner–Nordström–de Sitter (RN-dS) black hole surrounded by perfect fluid dark matter.

Euler–Heisenberg black hole surrounded by perfect fluid dark matter [PDF]
European Physical Journal C: Particles and FieldsA generation method of new metric in the case of static spherically symmetric space-time is derived. Using this approach, we construct a metric which describes Euler–Heisenberg black hole surrounded by perfect fluid dark matter and investigate its ...

Inhomogeneous Dark Fluid and Dark Matter, Leading to a Bounce Cosmology [PDF]
, 2015 The purpose of this short review is to describe cosmological models with a linear inhomogeneous time-dependent equation of state (EoS) for dark energy, when dark fluid is coupled with dark matter. This may lead to a bounce cosmology.

European Physical Journal C: Particles and FieldsIn this article, motivated by the high interest in Euler–Heisenberg nonlinear electrodynamic theory, we investigated several thermal aspects of the charged Euler–Heisenberg black hole surrounded by perfect fluid dark matter. To ensure the validity of the

The nature of phantom dark energy and its relation to time crystals [PDF]
Scientific ReportsIn this letter we show that, at its fundamental level, phantom dark energy is a fluid made up of time crystals that permeate the fabric of space-time.
