Many-body entanglement in fermion systems
N. Gigena, M. Di Tullio, R. Rossignoli
We introduce a general bipartite-like representation and Schmidt decomposition of an arbitrary pure state of indistinguishable fermions, based on states of and fe…
One-body entanglement as a quantum resource in fermionic systems
N. Gigena, M. Di Tullio, R. Rossignoli
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 single-pa…
Fermionic entanglement in the Lipkin model
M. Di Tullio, R. Rossignoli, M. Cerezo +1
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 entangleme…
Fermionic Entanglement in Superconducting Systems
M. Di Tullio, N. Gigena, R. Rossignoli
We examine distinct measures of fermionic entanglement in the exact ground state of a finite superconducting system. It is first shown that global measures such as the one-body ent…
