Interacting tachyon dark energy in non-flat universe
TL;DR: In this article, the tachyon cosmology in non-interacting and interacting cases in a non-flat FRW universe is studied. And the potential and the dynamics of the tACHYON field are reconstructed.
Journal ArticleDOI
Unimodular relativity and cosmological constant
TL;DR: In Lagrangian unimodular relativity as discussed by the authors, the covariant continuity holds and the cosmological constant is still a constant of integration of the gravitational field equations, even with higher derivatives of the dynamics.

Maxwell-like Lagrangians for higher spins
Andrea Campoleoni,Dario Francia +1 more
TL;DR: In this paper, a simple Lagrangian description of massless bosons of any spin is given. But the Lagrangians are invariant under divergence-free gauge transformations and the corresponding kinetic operators take essentially the same form as in the spin-one, Maxwell case.

Thermodynamical interpretation of the interacting holographic dark energy model in a non-flat universe
M. R. Setare,Elias C. Vagenas +1 more
TL;DR: In this paper, a thermodynamic interpretation for the holographic dark energy model in a non-flat universe is presented. But this interpretation is restricted to the case where the characteristic length is no more the radius of the event horizon (RE) but the radius as measured from the sphere of the horizon (L).
Journal ArticleDOI
Riemann-einstein structure from volume and gauge symmetry
TL;DR: In this paper, it is shown how a metric structure can be induced in a simple way starting with a gauge structure and a preferred volume, by spontaneous symmetry breaking, and a polynomial action, including coupling to matter, is constructed for the symmetric phase.
