Recent cosmological observations have posed a challenge for traditional theories of gravity:
what is the force driving the accelerated expansion of the universe? What if dark energy or …

Modified gravity theories with geometry-matter coupling, in which the action is an arbitrary
function of the Ricci scalar and the matter Lagrangian [f (R, L m) gravity], and of the Ricci …

We consider the possibility of a gravitationally induced particle production through the
mechanism of a nonminimal curvature–matter coupling. An interesting feature of this …

Entropic cosmology assumes several forms of entropy on the horizon of the universe, where
the entropy can be considered to behave as if it were related to the exchange (the transfer) …

We investigate the creation of cold dark matter (CCDM) cosmology as an alternative to
explain the cosmic acceleration. Particular attention is given to the evolution of density …

Particle creation (or annihilation) mechanisms, described by either quantum field theoretical
models, or by the thermodynamics of irreversible processes, play an important role in the …

We investigate the interaction between dark energy and dark matter in the framework of
irreversible thermodynamics of open systems with matter creation/annihilation. We consider …

The paper deals with the mechanism of particle creation in the framework of irreversible
thermodynamics. The second order nonequilibrium thermodynamical prescription of Israel …

We investigate warm intermediate scenario of the cosmological inflation in F (T) gravity in
the limit of high dissipation. The inflationary expansion is driven by the scalar inflaton while …

In a seminal paper, Alcubierre showed that Einstein's theory of general relativity appears to
allow a super-luminal motion. In the present study, we use a recent eternal-warp-drive …
