Hǒrava-Lifshitz Dark Energy
نویسنده
چکیده
We formulate Hořava-Lifshitz cosmology with an additional scalar field that leads to an effective dark energy sector. We find that, due to the inherited features from the gravitational background, Hořava-Lifshitz dark energy naturally presents very interesting behaviors, possessing a varying equation-of-state parameter, exhibiting phantom behavior and allowing for a realization of the phantom divide crossing. In addition, Hořava-Lifshitz dark energy guarantees for a bounce at small scale factors and it may trigger the turnaround at large scale factors, leading naturally to cyclic cosmology.

A Trouble with Hǒrava-Lifshitz Gravity
We study the structure of the phase space in Hořava-Lifshitz theory. With the constraints derived from the action, the phase space is described by five fields, thus there is a lack of canonical structure. The Poisson brackets of the Hamiltonian density do not form a closed structure, resulting in many new constraints. Taking these new constraints into account, it appears that there is no degree...
متن کاملDetailed balance in Hǒrava–Lifshitz gravity
We study Hořava–Lifshitz gravity in the presence of a scalar field. When the detailed balance condition is implemented, a new term in the gravitational sector is added in order to maintain ultraviolet stability. The four-dimensional theory is of scalar-tensor type with a positive cosmological constant and gravity is non-minimally coupled with the scalar and its gradient terms. The scalar field ...
متن کاملAsymptotically hyperbolic black holes in Hǒrava gravity
Solutions of Hořava gravity that are asymptotically Lifshitz are explored. General near boundary expansions allow the calculation of the mass of these spacetimes via a Hamiltonian method. Both analytic and numeric solutions are studied which exhibit a causal boundary called the universal horizon, and are therefore black holes of the theory. The thermodynamics of an asymptotically Anti-de Sitter...
متن کاملInteracting Dark Energy in Hořava-Lifshitz Cosmology
Motivated by the recent work of Saridakis [1], we generalize this work to the noninteracting case. Using an additional canonical scalar field, we formulate HořavaLifshitz cosmology with an effective interacting dark energy sector. ∗E-mail: [email protected]
متن کاملGalaxy Rotation Curves in Covariant Hořava-Lifshitz Gravity
Using the multiplicity of solutions for the projectable case of the covariant extension of Hořava-Lifshitz gravity, we show that an appropriate choice for the auxiliary field allows for an effective description of galaxy rotation curves. This description is based on static and spherically symmetric solutions of covariant Hořava-Lifshitz gravity and does not require Dark Matter.
