Multifractal approach to three-site antiferromagnetic Ising model
Abstract The three-site antiferromagnetic Ising model on Husimi tree is investigated in a magnetic field. Macroscopic quantity of the three-site antiferromagnetic Ising model is generated by aExpand

Multisite-interaction Ising model approach to the solid 3He system on a triangular lattice
We consider the Ising model with multiple-spin interactions on a recursive lattice of special type (the Bethe lattice of square plaquettes with additional inner link) as some approximation to theExpand

Antiferromagnetic Potts model: phase transition through doubling bifurcation
Abstract The antiferromagnetic Potts model in the magnetic field is rigorously considered on the Bethe lattice by means of a recursion relation. This allows one to study the critical properties ofExpand

Generation of entanglement in systems of intercoupled qubits
We consider systems of two and three qubits, mutually coupled by Heisenberg-type exchange interaction and interacting with external laser fields. We show that these systems allow one to createExpand

Thermal entanglement in an exactly solvable Ising- XXZ diamond chain structure
Most quantum entanglement investigations are focused on two qubits or some finite (small) chain structure, since the infinite chain structure is a considerably cumbersome task. Therefore, the quantumExpand

Thermal entanglement of a spin-1/2 Ising-Heisenberg model on a symmetrical diamond chain.
The entanglement quantum properties of a spin-1/2 Ising-Heisenberg model on a symmetrical diamond chain were analyzed. Due to the separable nature of the Ising-type exchange interactions betweenExpand

Phase diagrams and tricritical effects in the beg model
Abstract The critical properties of the spin-1 Ising model on the Bethe lattice with dipolar and quadrupolar exchange interactions are studied exactly. This method is based on recursion relations,Expand

Partition function zeros of the antiferromagnetic spin-12 Ising–Heisenberg model on a diamond chain
The partition function zeros of the antiferromagnetic spin-12 Ising–Heisenberg model on a diamond chain are studied using the transfer matrix method. Analytical equations for the distributions ofExpand

Quantum transitions, magnetization and thermal entanglement of the spin-1 Ising–Heisenberg diamond chain
Abstract We consider the quasi-one dimensional spin-1 Ising–Heisenberg model with single-ion anisotropy on a diamond chain. Due to the exact solution of the model, we constructed the ground stateExpand

Yang-Lee zeros of the Q-state Potts model on recursive lattices.
The Yang-Lee zeros of the Q-state Potts model on recursive lattices are studied for noninteger values of Q. Considering one-dimensional (1D) lattice as a Bethe lattice with coordination number equalExpand
