Logarithmic negativity of the 1D antiferromagnetic spin-1 Heisenberg model with single-ion anisotropy
Vladimir V. Papoyan, Giacomo Gori, Andrea Trombettoni +1
We study the 1D antiferromagnetic spin-1 Heisenberg XXX model with external magnetic field B and single-ion anisotropy D on finite chains. We determine the nearest and non-nearest…
Spin-1/2 Ising-Heisenberg Cairo pentagonal model in the presence of an external magnetic field: Effect of Landé g-factors
Hamid Arian Zad, Andrea Trombettoni, Nerses Ananikian
In the present paper, a study of the magnetic properties of a spin-1/2 Ising-Heisenberg Cairo pentagonal structure is presented. The model has been investigated in Ref. [34] in the…
Pairwise thermal entanglement in Ising-XYZ diamond chain structure in an external magnetic field
J. Torrico, M. Rojas, S. M. de Souza +2
Quantum entanglement is one of the most fascinating types of correlation that can be shared only among quantum systems. The Heisenberg chain is one of the simplest quantum chains w…
