Entanglement in fermion systems and quantum metrology
F. Benatti, R. Floreanini, U. Marzolino
Entanglement in fermion many-body systems is studied using a generalized definition of separability based on partitions of the set of observables, rather than on particle tensor pr…
Frustration, Entanglement, and Correlations in Quantum Many Body Systems
U. Marzolino, S. M. Giampaolo, F. Illuminati
We derive an exact lower bound to a universal measure of frustration in degenerate ground states of quantum many-body systems. The bound results in the sum of two contributions: en…
Entanglement robustness and geometry in systems of identical particles
F. Benatti, R. Floreanini, U. Marzolino
The robustness properties of bipartite entanglement in systems of N bosons distributed in M different modes are analyzed using a definition of separability based on commuting algeb…
Bipartite entanglement in systems of identical particles: the partial transposition criterion
F. Benatti, R. Floreanini, U. Marzolino
We study bipartite entanglement in systems of N identical bosons distributed in M different modes. For such systems, a definition of separability not related to any a priori Hilber…
Classical Statistical Mechanics Approach to Multipartite Entanglement
P. Facchi, G. Florio, U. Marzolino +2
We characterize the multipartite entanglement of a system of n qubits in terms of the distribution function of the bipartite purity over balanced bipartitions. We search for maxima…
Entangling two unequal atoms through a common bath
F. Benatti, R. Floreanini, U. Marzolino
The evolution of two, non-interacting two-level atoms immersed in a weakly coupled bath can be described by a refined, time coarse grained Markovian evolution, still preserving com…
