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…
Pair entanglement in dimerized spin-s chains
A. Boette, R. Rossignoli, N. Canosa +1
We examine the pair entanglement in the ground state of finite dimerized spin- chains interacting through anisotropic couplings immersed in a transverse magnetic field, by…
Pattern Recognition In Non-Kolmogorovian Structures
Federico Holik, Giuseppe Sergioli, Hector Freytes +1
We present a generalization of the problem of pattern recognition to arbitrary probabilistic models. This version deals with the problem of recognizing an individual pattern among…
Approximate transformations of bipartite pure-state entanglement from the majorization lattice
G. M. Bosyk, G. Sergioli, H. Freytes +2
We study the problem of deterministic transformations of an \textit{initial} pure entangled quantum state, , into a \textit{target} pure entangled quantum state, $|ϕ\ran…
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…
Unified entropic measures of quantum correlations induced by local measurements
G. M. Bosyk, G. Bellomo, S. Zozor +2
We introduce quantum correlations measures based on the minimal change in unified entropies induced by local rank-one projective measurements, divided by a factor that depends on t…
Quantumness and the role of locality on quantum correlations
Guido Bellomo, Angelo Plastino, Angel R. Plastino
Quantum correlations in a physical system are usually studied with respect to a unique (fixed) decomposition of the system into subsystems, without fully exploiting the rich struct…
