Entanglement Structures in Quantum Field Theories: Negativity Cores and Bound Entanglement in the Vacuum

Natalie Klco, D. H. Beck, Martin J. Savage

The many-body entanglement between two finite (size-$d$) disjoint vacuum regions of non-interacting lattice scalar field theory in one spatial dimension -- a $(d_A \times d_B)_{\rm…
