Insight into ground-state spin arrangement and bipartite entanglement of the polymeric coordination compound [DyCu] through the symmetric spin-1/2 Ising-Heisenberg orthogonal-dimer chain
Lucia Gálisová
The ground-state spin arrangement and the bipartite entanglement within Cu-Cu dimers across the magnetization process of the 4f-3d heterometallic coordination polymer…
Ground State, Magnetization Process and Bipartite Quantum Entanglement of a Spin-1/2 Ising-Heisenberg Model on Planar Lattices of Interconnected Trigonal Bipyramids
Lucia Gálisová, Michał Kaczor
The ground state, magnetization scenario and the local bipartite quantum entanglement of a mixed spin- Ising--Heisenberg model in a magnetic field on planar lattices formed by…
Enhanced magnetoelectric effect near a field-driven zero-temperature quantum phase transition of the spin-1/2 Heisenberg-Ising ladder
Jozef Strečka, Lucia Gálisová, Taras Verkholyak
Magnetoelectric effect of the spin-1/2 Heisenberg-Ising ladder in a presence of the external electric and magnetic fields is rigorously examined by taking into account Katsura-Naga…
Pairwise entanglement in double-tetrahedral chain with different Landé g-factors of the Ising and Heisenberg spins
Lucia Galisova
The pairwise entanglement is exactly examined in the spin-1/2 Ising-Heisenberg double-tetrahedral chain with different Landé g-factors of the Ising and Heisenberg spins at zero and…
Frustration phenomenon in the spin-1/2 Ising-Heisenberg planar model of inter-connected trigonal bipyramid structures
Lucia Galisova
Ground-state and finite-temperature properties of the exactly solvable mixed spin-1/2 Ising-Heisenberg planar model composed of identical trigonal bipyramids that are arranged into…
Macroscopic ground-state degeneracy and magnetocaloric effect in the exactly solvable spin-1/2 Ising-Heisenberg double-tetrahedral chain
Lucia Galisova, Dusan Knezo
The ground-state degeneracy and magnetocaloric effect in the spin- Ising-Heisenberg double-tetrahedral chain are exactly investigated. It is demonstrated that the zero-tempera…
