Dirac fermion, cosmological event horizons and quantum entanglement
Sourav Bhattacharya, Shankhadeep Chakrabortty, Shivang Goyal
We discuss the field quantisation of a free massive Dirac fermion in the two causally disconnected static patches of the de Sitter spacetime, by using mode functions that are norma…

Emergent -like fermionic vacuum structure and entanglement in the hyperbolic de Sitter spacetime
Sourav Bhattacharya, Shankhadeep Chakrabortty, Shivang Goyal
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 regio…
