I would like to introduce two kinds of holographic screens in flat spacetime, based on our 1705.05078 and some recent progress. One is the time-like hypersurface associated with an accelerating observer, where the Rindler fluid dual to flat spacetime is induced. The Rindler fluid can also be considered as the effective theory of the dual conformal fluid in AdS/CFT. The other one is the de Sitter hypersurface embedded into the flat spacetime, where the holographic stress tensor for the de Sitter universe can also be deduced. |
