### Hubble expansion and structure formation in time varying vacuum models

- Physics
- 2009

We investigate the properties of the FLRW flat cosmological models in which the vacuum energy density evolves with time, $\ensuremath{\Lambda}(t)$. Using different versions of the…

### Cosmological constant and vacuum energy: old and new ideas

- Physics
- 2013

The cosmological constant (CC) term in Einstein's equations, Λ, was first associated to the idea of vacuum energy density. Notwithstanding, it is well-known that there is a huge, in fact appalling,…

### Cosmological imprint of an energy component with general equation of state

- Physics
- 1998

We examine the possibility that a significant component of the energy density of the Universe has an equation of state different from that of matter, radiation, or cosmological constant ({Lambda} ).…

### The $\bar{\Lambda}{\rm CDM}$ cosmology: From inflation to dark energy through running Λ

- Physics
- 2015

Perhaps the deepest mystery of our accelerating universe in expansion is the existence of a tiny and rigid cosmological constant, Λ. Its size is many orders of magnitude below the expected one in the…

### Particle Physics and Inflationary Cosmology

- Physics, EducationPhysics Today
- 1987

With the invention of unified theories of strong, weak, electromagnetic and gravitational interactions, elementaryparticle physics has entered a very interesting and unusual stage of its development.…

### Vacuum models with a linear and a quadratic term in H: structure formation and number counts analysis

- Physics
- 2015

We focus on the class of cosmological models with a time-evolving vacuum energy density of the form $\rho_\Lambda=C_0+C_1 H+C_2 H^2$, where $H$ is the Hubble rate. Higher powers of $H$ could be…

### The Primordial Density Perturbation

- Physics
- 2009

The origin and evolution of the primordial perturbation is the key to understanding structure formation in the earliest stages of the Universe. It carries clues to the types of physical phenomena…

### The cosmological constant puzzle

- Physics
- 2011

The accelerating expansion of the Universe points to a small positive vacuum energy density and negative vacuum pressure. A strong candidate is the cosmological constant in Einstein's equations of…

### Cosmological consequences of a time-dependent Lambda term.

- PhysicsPhysical review. D, Particles and fields
- 1992

The phenomenological approach to investigate the decay of the effective cosmological constant is generalized to include a term proportional to ${H}^{2}$ on the time dependence of $\ensuremath{\Lambda}$, where $H$ is the Hubble parameter.
