Magnetization plateaus and enhanced magnetocaloric effect of a spin-1/2 Ising-Heisenberg and Heisenberg double sawtooth ladder with four-spin interaction
Hamid Arian Zad, Vadim Ohanyan, Azam Zoshki +1
The ground state, the entropy and the magnetic Grüneisen parameter of the antiferromagnetic spin-1/2 Ising-Heisenberg model on a double sawtooth ladder are rigorously investigated…
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…
Robust quantum entanglement and teleportation in the tetrapartite spin-1/2 square clusters: Theoretical study on the effect of a cyclic four-spin exchange
Hamid Arian Zad, Azam Zoshki, Nerses Ananikian +1
The whole entanglement measure so-called geometric average of tangles and bipartite entanglement of the antiferromagnetic spin-1/2 XXX Heisenberg model on a tetranuclear squa…
Enhanced magnetocaloric effect in a mixed spin-(1/2, 1) Ising-Heisenberg two-leg ladder with strong-rung interaction
Hamid Arian Zad, Nerses Ananikian
The magnetic and magnetocaloric properties of the mixed spin-(1/2,1) Ising-Heisenberg model on a two-leg ladder with dimer-rung alternation are exactly examined under an adiabatic…
Magnetic and thermodynamic properties of the octanuclear nickel phosphonate-based cage
Hamid Arian Zad, Ralph Kenna, Nerses Ananikian
We report a detailed theoretical investigation into the influence of anisotropy on the magnetic and thermodynamic properties of an octanuclear nickel phosphonate cage with butterfl…
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…
The specific heat and magnetic properties of a spin-1/2 ladder including butterfly-shaped unit blocks
Hamid Arian Zad
The specific heat, structural characterization, and magnetic property studies of a new spin ladder with the geometry of butterfly-shaped configuration are reported. The model intro…
