Contribution

It introduces and analyzes a class of dynamic braneworld models with standing waves, highlighting their localization mechanisms and cosmological relevance.

Findings

Matter particles can be localized at standing wave nodes.

The models exhibit solutions with bulk gravi-scalar standing waves.

Cosmological applications of these models are discussed.

Abstract

The class of non-stationary braneworld models generated by the coupled gravitational and scalar fields is reviewed. The model represents a brane in a space-time with single time and one large (infinite) and several small (compact) space-like extra dimensions. In some particular cases the model has the solutions corresponding to the bulk gravi-scalar standing waves bounded by the brane. Pure gravitational localization mechanism of matter particles on the node of standing waves, where the brane is placed, is discussed. Cosmological applications of the model also considered.
