Bounds on mixed state entanglement
Bruno Leggio, Anna Napoli, Hiromichi Nakazato +1
In the general framework of mixed states, we derive an explicit bound for bipartite NPT entanglement based on the mixedness characterization of the physical system. The…
Hilbert space partitioning for non-Hermitian Hamiltonians: From off-resonance to Zeno subspaces
Benedetto Militello, Anna Napoli
Effective non-Hermitian Hamiltonians describing decaying systems are derived and analyzed in connection with the occurrence of possible Hilbert space partitioning, resulting in a c…
Energy bounds for entangled states
Nicolò Piccione, Benedetto Militello, Anna Napoli +1
We find the minimum and the maximum value for the local energy of an arbitrary finite bipartite system for any given amount of entanglement, also identifying families of states rea…
