Classification of quantum states through conserved operators
Federico Petrovich, R. Rossignoli, M. Cerezo
Determining whether quantum states can be interconverted by a prescribed set of transformations is a fundamental problem in quantum information. Here we develop a general classific…
Conserved operators and exact conditions for pair condensation
Federico Petrovich, R. Rossignoli
We determine the necessary and sufficient conditions which ensure that an -particle fermionic or bosonic state has the form , wher…
Bipartite representations and many-body entanglement of pure states of indistinguishable particles
J. A. Cianciulli, R. Rossignoli, M. Di Tullio +2
We analyze a general bipartite-like representation of arbitrary pure states of indistinguishable particles, valid for both bosons and fermions, based on - and -partic…
Covariance-based method for eigenstate factorization and generalized singlets
Federico Petrovich, R. Rossignoli, N. Canosa
We derive a general method for determining the necessary and sufficient conditions for exact factorization of an eigenstate of a many-body Hamilto…
Ground state separability and criticality in interacting many-particle systems
F. Petrovich, N. Canosa, R. Rossignoli
We analyze exact ground state (GS) separability in general particle systems with two-site couplings. General necessary and sufficient conditions for full separability, in the f…
