“…Interestingly, it could be mapped to the moving membrane on the holographic cutoff, where the Brown-York stress-energy tensor on the membrane is identified with that of the holographic dark fluid. As has been studied in [42], if we take In order to determine C 2 , we firstly note that C 2 can be a function of the time coordinate t without any dependence on w. Thus, we can solve C 2 just on the brane where w = 0. Note that on the brane, the (ww)-component equation in Eq.…”

We consider the holographic Friedman-Robertson-Walker (hFRW) universe on the 4dimensional membrane embedded in the 5-dimensional bulk spacetime, and fit the parameters with the observational data. In order to fully account for the phenomenology of this scenario, we consider the models with the brane cosmological constant and the negative bulk cosmological constant. The contribution from the bulk is represented as the holographic dark fluid on the membrane. We derive the universal modified Friedmann equation by including all of these effects in both braneworld and holographic cutoff approaches. For three specific models, namely, the pure hFRW model, the one with the brane cosmological constant, and the one with the negative bulk cosmological constant, we compare the model predictions

“…For the models which consider the universe as the boundary of 4+1 dimensional AdS [52][53][54][55][56][57][58], there is an effective contribution from the holographic stress-energy tensor, which can be identified as the stress-energy tensor of dark energy and/or dark matter. In our construction, the holographic screen is embedded into one higher dimensional flat spacetime, which is inspired by the holographic hydrodynamics in Rindler spacetime [42,43,[76][77][78][79][80][81][82]. It is named as Rindler fluid, which is described by the Brown-York stress-energy tensor on the accelerating cutoff hypersurface in a flat bulk.…”

We discuss a scenario that the dark matter in late time universe emerges as part of the holographic stress-energy tensor on the hypersurface in higher dimensional flat spacetime. Firstly we construct a toy model with a de Sitter hypersurface as the holographic screen in the flat bulk. After adding the baryonic matter on the screen, we assume that both of the dark matter and dark energy can be described by the Brown-York stress-energy tensor. From the Hamiltonian constraint equation in the flat bulk, we find an interesting relation between the dark matter and baryonic matter's energy density parameters, by comparing with the Lambda cold dark matter parameterization. We further compare this holographic embedding of emergent dark matter with traditional braneworld scenario and present an alternative interpretation as the holographic universe. It can be reduced to our toy constraint in the late time universe, with the new parameterization of the Friedmann equation. We also comment on the possible connection with Verlinde's emergent gravity, where the dark matter is treated as the elastic response of the baryonic matter on the de Sitter spacetime background. We show that from the holographic de Sitter model with elasticity, the Tully-Fisher relation and the dark matter distribution in the galaxy scale can be derived.

“…Where the holographic stress-energy tensor on the holographic cutoff surface is identified with the stress energy tensor of the dual fluid directly. When taking the near horizon limit, one can reach the so-called Rindler fluid [15][16][17][18][19][20][21][22], which is a new perspective on the membrane paradigm of black holes, where the Brown-York stress-energy tensor is used.…”
