Genuine Tripartite Entanglement in a Spin-Star Network at Thermal Equilibrium

Risultato della ricerca: Articlepeer review

15 Citazioni (Scopus)


In a recent paper [M. Huber et al, Phys. Rev. Lett. 104, 210501 (2010)] new criteria to find out the presence ofmultipartite entanglement have been given. We exploit these toolsin order to study thermal entanglement in a spin-star network madeof three peripheral spins interacting with a central one. Genuinetripartite entanglement is found in a wide range of the relevantparameters. A comparison between predictions based on the newcriteria and those based on the tripartite negativity is also made.
