Entanglement and coherence in a spin-s XXZ system under non-uniform fields
E. Rios, R. Rossignoli, N. Canosa
We investigate entanglement and coherence in an spin- pair immersed in a non-uniform transverse magnetic field. The ground state and thermal entanglement phase diagrams ar…
One-body information loss in fermion systems
N. Gigena, R. Rossignoli
We propose an entropic measure of non-classical correlations in general mixed states of fermion systems, based on the loss of information due to the unread measurement of the occup…
Separability conditions and limit temperatures for entanglement detection in two qubit Heisenberg XYZ models
N. Canosa, R. Rossignoli
We examine the entanglement of general mixed states of a two qubit Heisenberg XYZ chain in the presence of a magnetic field, and its detection by means of different criteria. Both…
Factorization in XYZ spin systems under general fields and separable ground state engineering
M. Cerezo, R. Rossignoli, N. Canosa
We discuss ground state factorization schemes in spin arrays with general couplings under general magnetic fields, not necessarily uniform or transverse. It is first show…
