Abstract

We consider a deformed version of four-dimensional de Sitter spacetime. The setup consist of two (antipodal) disconnected Rindler observers, each one with an S4 topology. We show that the two observers have an entanglement entropy, in the low energy sector, given by a quarter of the area of a pair minimal surfaces, that corresponds to the set of fixed points of an Zq orbifold. The result matches with the Gibbons-Hawking entropy when we restrict the Zq action to a single Rindler wedge.
