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 ${\…
Quantum Heisenberg antiferromagnet in a field on the Tasaki square lattice
Maksym Parymuda, Taras Krokhmalskii, Oleg Derzhko
We consider the Heisenberg antiferromagnet on the Tasaki square lattice (flat-band spin system) and study its low-temperature thermodynamics around the saturation magnetic…
Three-dimensional unfrustrated and frustrated quantum Heisenberg magnets. Specific heat study
T. Krokhmalskii, T. Hutak, O. Derzhko
We examine the Heisenberg magnet on four three-dimensional lattices - simple-cubic, diamond, pyrochlore, and hyperkagome ones - for ferromagnetic and antiferromagnetic sign…
Thermodynamics of the hyperkagome-lattice Heisenberg ferromagnet
Maksym Parymuda, Taras Krokhmalskii, Oleg Derzhko
The hyperkagome-lattice Heisenberg ferromagnet is studied by means of the linear spin-wave theory, the double-time temperature Green's function method, high-temperature exp…
Frustrated kagome-lattice bilayer quantum Heisenberg antiferromagnet
Dmytro Yaremchuk, Taras Hutak, Vasyl Baliha +4
We consider the antiferromagnetic Heisenberg model on a frustrated kagome-lattice bilayer with strong nearest-neighbor interlayer coupling and examine its low-temperature m…
Thermodynamics of the hyperkagome-lattice Heisenberg antiferromagnet
Taras Hutak, Taras Krokhmalskii, Jürgen Schnack +2
The hyperkagome-lattice Heisenberg antiferromagnet allows to study the interplay of geometrical frustration and quantum as well as thermal fluctuations in three dimensions.…
