Back and forth from Fock space to Hilbert space: a guide for commuters
Andrea Beggi, Ilaria Siloi, Claudia Benedetti +4
Quantum states of systems made of many identical particles, e.g. those described by Fermi-Hubbard and Bose-Hubbard models, are conveniently depicted in the Fock space. However, in…
Probing the sign of on-site Hubbard interaction by two-particle quantum walks
Andrea Beggi, Luca Razzoli, Paolo Bordone +1
We consider two identical bosons propagating on a one-dimensional lattice and address the prob- lem of discriminating whether their mutual on-site interaction is attractive or repu…
Quantum correlations of identical particles subject to classical environmental noise
Andrea Beggi, Fabrizio Buscemi, Paolo Bordone
In this work we propose a measure for the quantum discord of indistinguishable particles, based on the definition of entanglement of particles given in [H. M. Wiseman et al., Phis.…
Analytical expression of Genuine Tripartite Quantum Discord for Symmetrical X-states
Andrea Beggi, Fabrizio Buscemi, Paolo Bordone
The study of classical and quantum correlations in bipartite and multipartite systems is crucial for the development of quantum information theory. Among the quantifiers adopted in…
