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…
Multiphoton excitation and high harmonic generation in rectangular graphene quantum dot
A G Ghazaryan, Kh V Sedrakian
The multiphoton excitation and high harmonic generation (HHG) processes are considered using the microscopic quantum theory of nonlinear interaction of strong coherent electromagne…
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…
An RF Timer of Electrons and Photons with the Potential to reach Picosecond Precision
Amur Margaryan, Vanik Kakoyan, Simon Zhamkochyan +17
This paper describes a new radio frequency timer of keV energy electrons. It is based on a helical deflector, which performs circular or elliptical sweeps of keV electrons, by mean…
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…
Spin-1/2 chain in a transverse field with regularly alternating -factors: Static and dynamic properties
Taras Krokhmalskii, Taras Verkholyak, Ostap Baran +2
We consider the spin-1/2 isotropic chain in an external magnetic field directed along axis with periodically varying -factors. To reveal the effects of regularly altern…
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…
Electrocaloric effect in the two spin-1/2 XXZ Heisenberg edge-shared tetrahedra and spin-1/2 XXZ Heisenberg octahedron with Dzyaloshinskii-Moriya interaction
Hamid Arian Zad, Moones Sabeti, Azam Zoshki +1
In the present paper, we consider two species of small spin clusters known as; two spin-1/2 Heisenberg edge-shared tetrahedra and spin-1/2 Heisenberg octahedron with the correspond…
Magnetic and magnetoelectric properties of FeF ( = Ca, Sr) spin-chain compounds
N. V. Ter-Oganessian, S. A. Guda, V. P. Sakhnenko +1
Fluorides in general are characterized by big variety of crystal structures, whereas those containing transition metals also often show sizable magnetic properties. The tendency of…
