|TITLE||Emergent dark matter in late universe|
We discuss a scenario that the dark matter in late universe emerges as part of the holographic stress-energy tensor on the hypersurface in higher dimensional flat bulk. We construct a toy model with a de Sitter hypersurface in flat spacetime. After adding the baryonic matter on the screen, both of the dark matter and dark energy can be described by the Brown-York stress-energy tensor. We find an interesting relation between the dark matter and baryonic matter density parameters, by using the Lambda cold dark matter parameterization.
