Manipulation of electromagnetic wave propagation in quantum-spin-chain medium
Taras Krokhmalskii, Taras Verkholyak, Ostap Baran +3
We consider a simple model of one-dimensional magnetic crystal and examine the propagation of an electromagnetic wave through such a medium. Calculating the dispersion relation ${\…
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…
Reference approach in theory of pseudospin systems
R. R. Levitskii, S. I. Sorokov, O. R. Baran
For theoretical description of pseudospin systems with essential short-range and long-range interactions we use the method based on calculations of the free energy functional with…
Pair correlation functions of the Ising type model with spin 1 within two-particle cluster approximation
O. R. Baran, R. R. Levitskii
The Blume-Emery-Griffiths model on hypercubic lattices within the two-particle cluster approximation is investigated. The expressions for the pair correlation functions in …
Phase diagrams of spin-1 Ising model with bilinear and quadrupolar interactions under magnetic field. Two-particle cluster approximation
R. R. Levitskii, O. R. Barana, B. M. Lisnii
The spin-1 Ising model with bilinear and quadrupolar short-range interactions under magnetic field is investigated within the two-particle cluster approximation. It is shown that f…
Influence of transverse field on the spin-3/2 Blume-Capel model on rectangular lattice
O. Baran, R. Levitskii
Transverse field effect on thermodynamic properties of the spin-3/2 Blume-Capel model on rectangular lattice in which the interactions in perpendicular directions differ in signs i…
Phase diagrams of spin-3/2 Blume-Capel model on rectangular lattice under longitudinal magnetic field
O. Baran, R. Levitskii
The spin-3/2 Blume-Capel model on a rectangular lattice with the ferromagnetic bilinear short-range interaction in one direction and the anti-ferromagnetic one $…
Spin-1/2 XY chain magnetoelectric: effect of zigzag geometry
Ostap Baran, Vadim Ohanyan, Taras Verkholyak
A spin-1/2 chain model of magnetoelectric on a zigzag chain is considered rigorously. The magnetoelectric coupling is described within the Katsura-Nagaosa-Balatsky mechanism.…
