Holography and Brane-bulk Energy Exchange
The five-dimensional description of generalized Randall-Sundrum cosmology is mapped via holography to a generalization of the Starobinsky model. This provides a holographic dual description of the cosmological brane-bulk energy exchange processes studied previously. Some simple solutions are presented in four dimensions.
متن کامل7D Randall–Sundrum cosmology, brane–bulk energy exchange and holography
We discuss the cosmological implications and the holographic dual theory of the 7D Randall–Sundrum (RS) gravitational set–up. Adding generic matter in the bulk on the 7D gravity side we study the cosmological evolution inferred by the non vanishing value of the brane–bulk energy exchange parameter. This analysis is achieved in detail for specific assumptions on the internal space evolution, inc...
متن کاملNegative Energy, Superluminosity and Holography
The holographic connection between large N Super Yang Mills theory and gravity in anti deSitter space requires unfamiliar behavior of the SYM theory in the limit that the curvature of the AdS geometry becomes small. The paradoxical behavior includes superluminal oscillations and negative energy density. These effects typically occur in the SYM description of events which take place far from the...
متن کاملHolography and holographic dark energy model
The holographic principle is used to discuss the holographic dark energy model. We find that the Bekenstein-Hawking entropy bound is far from saturation under certain conditions. A more general constraint on the parameter of the holographic dark energy model is also derived.

متن کاملMultiple scattering in low-energy electron holography
The theory of the low-energy electron point source (LEEPS) microscope is reformulated in matrix form to readily account for multiple scattering. An algorithm is developed for the storage of the structure matrix and an iterative method is used to solve the matrix equation for the structure factor. Examples of small and large clusters of atoms are given to compare single and multiple scattering. ...
