- Abstract summary: We study the genuine N-partite entanglement and distributed relationships for Dirac fields in the background of black holes.
We find that the accessible N-partite entanglement exhibits irreversible decoherence as the increase of black hole's dilaton.
We also find two distributed relationships between accessible and inaccessible N-partite entanglement in curved spacetime.

- Abstract: With the complexity of information tasks, the bipartite and tripartite
entanglement can no longer meet our needs, and we need more entangled particles
to process relativistic quantum information. In this paper, we study the
genuine N-partite entanglement and distributed relationships for Dirac fields
in the background of dilaton black holes. We present the general analytical
expression including all physically accessible and inaccessible entanglement in
curved spacetime. We find that the accessible N-partite entanglement exhibits
irreversible decoherence as the increase of black hole's dilaton, and on the
other hand the inaccessible N-partite entanglement increases from zero
monotonically or non-monotonically, depending on the relative numbers of the
accessible to the inaccessible modes, which forms a sharp contrast with the
cases of bipartite and tripartite entanglement where the inaccessible
entanglement increase only monotonically. We also find two distributed
relationships between accessible and inaccessible N-partite entanglement in
curved spacetime. The results give us a new understanding of the Hawking
radiation.

We study the N-partite coherences of GHZ and W states for free bosonic and fermionic fields when any n observers hover near the event horizon of a Garfinkle-Horowitz-Strominger dilaton black hole.
It has been found that the coherence of the bosonic field is greater than that of the fermionic field, while the entanglement of the fermionic field is greater than that of the bosonic field in dilaton spacetime.

We take advantage of the clean setting of homogeneous quantum gases and fast radio-frequency control to manipulate Fermi polarons.

We observe that the entanglement phase transitions occurring in the stationary state have the same nature as that occurring in the vacuum of the non-hermitian Hamiltonian.
