Dynamics of dark energy
TL;DR: In this article, the authors review the observational evidence for the current accelerated expansion of the universe and present a number of dark energy models in addition to the conventional cosmological constant, paying particular attention to scalar field models such as quintessence, K-essence and tachyon.

4D Gravity on a Brane in 5D Minkowski Space
TL;DR: In this article, the authors propose a mechanism by which four-dimensional Newtonian gravity emerges on a 3-brane in 5D Minkowski space with an infinite size extra dimension.
Journal ArticleDOI
A model of holographic dark energy
TL;DR: In this article, a model for holographic dark energy is proposed, following the idea that the short distance cutoff is related to the infrared cut-off, and the model predicts the equation of state of the dark energy at the present time to be characterized by w = -0.90.
Journal ArticleDOI
Essentials of k essence
TL;DR: In this article, the basic theory of k-essence and dynamical attractors based on evolving scalar fields with nonlinear kinetic energy terms in the action is presented, and guidelines for constructing concrete examples and show that there are two classes of solutions.
Journal ArticleDOI
Effective field theory, black holes, and the cosmological constant
TL;DR: In this article, a relationship between UV and IR cutoffs is proposed to reconcile the success of local quantum field theory in describing observed particle phenomenology, such that an effective field theory should be a good description of nature.
