Conservative Force Fields in Non-Gaussian Statistics

J. M. Silva, R. Silva, J. A. S. Lima

In this letter, we determine the -distribution function for a gas in the presence of an external field of force described by a potential U(). In the case of a dilute ga…

Hybrid dark energy

J. S. Alcaniz, R. Silva, F. C. Carvalho +1

Extending previous results [Phys. Rev. Lett. 97, 081301 (2006)], we explore the cosmological implications of a new quintessence scenario driven by a slow rolling homogeneous scalar…

CMB and LSS constraints on a single-field model of inflation

F. C. Carvalho, J. S. Alcaniz, J. A. S. Lima +1

A new inflationary scenario whose exponential potential has a quadratic dependence on the field in addition to the standard linear term is confronted with the tree-year…

Scalar-field-dominated cosmology with a transient accelerating phase

F. C. Carvalho, J. S. Alcaniz, J. A. S. Lima +1

A new cosmological scenario driven by a slow rolling homogeneous scalar field whose exponential potential has a quadratic dependence on the field in addition to the stan…

Non-extensive statistics and the stellar polytrope index

R. Silva, J. S. Alcaniz

We use physical constrains imposed from the H-Theorem and from the negative nature of the heat capacity of self-gravitating thermodynamically isolated systems to investigate some p…

Negative heat capacity and non-extensive kinetic theory

R. Silva, J. S. Alcaniz

The negative nature of the heat capacity of thermodynamically isolated self-gravitating systems is rediscussed in the framework of a non-extensive kinetic theory. It is found…
