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…
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…
