Braneworlds and Dark Energy

چکیده
In the Randall-Sundrum scenario we analyze the dynamics of an AdS5 braneworld when conformal matter fields propagate in 5-dimensions. We show that conformal fields of weight −4 are associated with stable geometries which describe the dynamics of inhomogeneous dust, generalized dark radiation and homogeneous polytropic dark energy on a spherically symmetric 3-brane embedded in the compact AdS5 orbifold. We discuss aspects of the radion stability conditions and of the localization of gravity in the vicinity of the brane.

Braneworlds, Conformal Fields and the Gravitons
We investigate the dynamics of Randall-Sundrum AdS5 braneworlds with 5-dimensional conformal matter fields. In the scenario with a compact fifth dimension the class of conformal fields with weight -4 is associated with exact 5-dimensional warped geometries which are stable under radion field perturbations and describe on the brane the dynamics of inhomogeneous dust, generalized dark radiation a...
متن کاملBraneworlds, Conformal Fields and Dark Energy
In the Randall-Sundrum scenario we analize the dynamics of a spherically symmetric 3-brane when matter fields propagate in the bulk. For a well defined class of conformal fields of weight -4 we determine a new set of exact 5-dimensional solutions which localize gravity in the vicinity of the brane and are stable under radion field perturbations. Geometries which describe the dynamics of inhomog...
متن کاملIndirect signals from braneworlds
It has been suggested that our universe could be a 3-dimensional brane where the SM fields live embedded in a D-dimensional space-time. In flexible braneworlds, in addition to the SM fields, new degrees of freedom appear on the brane associated to brane fluctuations. These new fields, known as branons, are standard WIMPs (Weakly Interacting Massive Particles) and therefore natural dark matter c...
متن کاملCosmological solutions of model with 1 / H 2 term
We drive the cosmological solutions of five-dimensional model with 1/H2 term (H2 ≡ HMNPQH), where HMNPQ is 4-form field strength. The behaviors of the scale factors and the scalar potential in effective theory are examined. As a consequence, we show that the universe changes from decelerated expansion to accelerated expansion in Einstein frame of the four-dimensional theory. [email protected]...
متن کاملCFTs on Non-Critical Braneworlds
We examine the cosmological evolution equations of de Sitter, flat and anti-de Sitter braneworlds sandwiched in between two n dimensional AdSSchwarzschild spacetimes. We are careful to use the correct form for the induced Newton’s constant on the brane, and show that it would be naive to assume the energy of the bulk spacetime is just given by the sum of the black hole masses. By carefully calc...
