One-body entanglement as a quantum resource in fermionic systems

N Gigena, M Di Tullio, R Rossignoli - Physical Review A, 2020 - APS
We show that one-body entanglement, which is a measure of the deviation of a pure
fermionic state from a Slater determinant (SD) and is determined by the mixedness of the …

Many-body entanglement in fermion systems

N Gigena, M Di Tullio, R Rossignoli - Physical Review A, 2021 - APS
We discuss a general bipartitelike representation and Schmidt decomposition of an arbitrary
pure state of N indistinguishable fermions, based on states of M< N and (NM) fermions. It is …

Bipartite representations and many-body entanglement of pure states of indistinguishable particles

JA Cianciulli, R Rossignoli, M Di Tullio, N Gigena… - Physical Review A, 2024 - APS
We analyze a general bipartite-like representation of arbitrary pure states of N
indistinguishable partcles, valid for both bosons and fermions, based on M-and (N− M) …

Fermionic entanglement in the Lipkin model

M Di Tullio, R Rossignoli, M Cerezo, N Gigena - Physical Review A, 2019 - APS
We examine the fermionic entanglement in the ground state of the fermionic Lipkin model
and its relation with bipartite entanglement. It is first shown that the one-body entanglement …

Entrelazamiento y correlaciones en sistemas fermiónicos

M Di Tullio - 2021 - sedici.unlp.edu.ar
La extensión del concepto de entrelazamiento a sistemas de componentes indistinguibles, y
en particular a sistemas fermiónicos es un problema fundamental que ha recientemente …
