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 ${\…
Thermodynamic properties of the macroscopically degenerate tetramer-dimer phase of the spin-1/2 Heisenberg model on the diamond-decorated square lattice
Katarina Karlova, Andreas Honecker, Nils Caci +3
The spin-1/2 Heisenberg antiferromagnet on the diamond-decorated square lattice in the presence of a magnetic field displays various quantum phases including the Lieb-Mattis ferrim…
Phases of the spin-1/2 Heisenberg antiferromagnet on the diamond-decorated square lattice in a magnetic field
Nils Caci, Katarina Karlova, Taras Verkholyak +3
The spin-1/2 Heisenberg antiferromagnet on the frustrated diamond-decorated square lattice is known to feature various zero-field ground-state phases, consisting of extended monome…
Insights into nature of a magnetization plateau of 3-4 coordination polymer [DyCu] from a spin-1/2 Ising-Heisenberg orthogonal-dimer chain
J. Strečka, L. Gálisová, T. Verkholyak
The ground state and magnetization process of an exactly solved spin- Ising-Heisenberg orthogonal-dimer chain with two different gyromagnetic factors of the Ising and Heisenbe…
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…
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.…
