Emergent $$\alpha $$ α -like fermionic vacuum structure and entanglement in the hyperbolic de Sitter spacetime
Abstract We report a non-trivial feature of the vacuum structure of free massive or massless Dirac fields in the hyperbolic de Sitter spacetime. Here we have two causally disconnected regions, say R and L separated by another region, C. We are interested in the field theory in $$R\cup L$$ R∪L to und...
