### Fractional dark energy: Phantom behavior and negative absolute temperature

- PhysicsPhysical Review D
- 2021

The fractional dark energy (FDE) model describes the accelerated expansion of the Universe through a nonrelativistic gas of particles with a noncanonical kinetic term. This term is proportional to…

### Quantum mechanical look at the radioactive-like decay of metastable dark energy

- Physics
- 2017

We derive the Shafieloo, Hazra, Sahni and Starobinsky (SHSS) phenomenological formula for the radioactive-like decay of metastable dark energy directly from the principles of quantum mechanics. To…

### KSVZ axion model with quasidegenerate minima: A unified model for dark matter and dark energy

- PhysicsPhysical Review D
- 2019

We consider the possibility that dark matter and dark energy can be explained by the minimal Kim-Shifman-Vainshtein-Zakharov axion model. This is possible if the lowest energy minimum of the scalar…

### Fractional dark energy

- Physics
- 2021

In this paper we introduce the fractional dark energy model, in which the accelerated expansion of the Universe is driven by a non-relativistic gas (composed by either fermions or bosons) with a…

### Cosmological implications of the transition from the false vacuum to the true vacuum state

- Physics
- 2016

We study cosmology with running dark energy. The energy density of dark energy is obtained from the quantum process of transition from the false vacuum state to the true vacuum state. We use the…

### Dark energy, scalar singlet dark matter and the Higgs portal

- Physics
- 2017

One of the simplest extensions of the Standard Model (SM) comprises the inclusion of a massive real scalar field, neutral under the SM gauge groups, to be a dark matter candidate. The addition of a…

### Cosmological implications of metastable dark energy with the decay law derived from Quantum Mechanics

- Physics
- 2017

We follow Krauss and Dent's paper and apply the Fock-Krylov theory of quantum unstable states to analyse a cosmological scenario with decaying dark energy. For this purpose we extend the Shafieloo,…

### A universe born in a metastable false vacuum state needs not die

- Physics
- 2022

We try to ﬁnd conditions, the fulﬁllment of which allows a universe born in a metastable false vacuum state to survive and not to collapse. The conditions found are in the form of inequalities…

### Cosmologia do setor escuro

- Physics
- 2017

The dark side of the universe is mysterious and its nature is still unknown. In fact, this poses perhaps as the biggest challenge in the modern cosmology. The two components of the dark sector (dark…

### Metastable Dark Energy with Radioactive-like Decay

- Physics
- 2018

We propose a new class of metastable dark energy (DE) phenomenological models in which the DE decay rate does not depend on external parameters such as the scale factor or the curvature of the…

### Dark energy, the colored anti-de Sitter vacuum, and LHC phenomenology

- Physics

We study the possibility that the current accelerated expansion of the universe is driven by the vacuum energy density of a colored scalar ﬁeld which is responsible for a phase transition in which…

### Interacting Dark Matter and Dark Energy

- Physics
- 2003

We discuss models for the cosmological dark sector in which the energy density of a scalar field approximates Einstein's cosmological constant and the scalar field value determines the dark matter…

### Cosmology with interaction between phantom dark energy and dark matter and the coincidence problem

- Physics
- 2005

We study a cosmological model in which phantom dark energy is coupled to dark matter by phenomenologically introducing a coupled term to the equations of motion of dark energy and dark matter. This…

### Coupled dark energy: towards a general description of the dynamics

- Physics

In dark energy models of scalar-field coupled to a barotropic perfect fluid, the existence of cosmological scaling solutions restricts the Lagrangian of the field φ to p = Xg(Xeλφ), where , λ is a…

We review in detail a number of approaches that have been adopted to try and explain the remarkable observation of our accelerating universe. In particular we discuss the arguments for and recent…

### Phenomenology of left-right symmetric dark matter

- Physics

We present a detailed study of dark matter phenomenology in low-scale left-right symmetric models. Stability of new fermion or scalar multiplets is ensured by an accidental matter parity that…

### Massive Photon and Dark Energy

- Physics
- 2016

We investigate cosmology of massive electrodynamics and explore the possibility whether massive photon could provide an explanation of the dark energy. The action is given by the scalar-vector-tensor…
