Spins extracted from fermionic states and their entanglement properties
Filippo Troiani, Andrea Secchi, Stefano Pittalis
We investigate the spin states obtained by extracting electrons from closed-shell fermionic states. A partition of the system is defined through the introduction of the extract…

Genuine multipartite entanglement from many-electron systems
Filippo Troiani, Celestino Angeli, Andrea Secchi +1
We demonstrate that, contrary to common wisdom, genuine multipartite entanglement (GME) can be abundantly generated from simple non-correlated many-electron states. We show that th…
