Thermodynamic and magnetic properties of the Ising model with nonmagnetic impurities
D. N. Yasinskaya, Yu. D. Panov
We consider a system of Ising spins s=1/2 with nonmagnetic impurities with charge associated with pseudospin S=1. The charge density is fixed pursuant to the concentration n. Analy…
Zero temperature phase transitions and their anomalous influence on thermodynamic behavior in the q-state Potts model on a diamond chain
Yury Panov, Onofre Rojas
The q-state Potts model on a diamond chain has mathematical significance in analyzing phase transitions and critical behaviors in diverse fields, including statistical physics, con…
Topological structures in unconventional scenario for 2D cuprates
A. S. Moskvin, Yu. D. Panov
We introduce a minimal model to describe the charge degree of freedom in cuprates with the on-site Hilbert space reduced to only the three valence states CuO (nomina…
Influence of Local Correlations on the "Homogeneous Insulator-Superconductor" Transition in the Domain Boundaries of the Charge-Order Phase of a 2D System of a Mixed Valence
V. V. Konev, V. A. Ulitko, D. N. Yasinskaya +2
It is demonstrated in the (pseudo)spin S=1 formalism that the structure of antiphase domain boundaries in the phase of charge ordering of a mixed-valence system of the Cu1+, 2+, 3+…
Competition between the Spin and Pseudospin Subsystems in a Model Cuprate
Yu. D. Panov, V. A. Ulitko, K. S. Budrin +2
The competition between the magnetic and charge orderings in a model cuprate is considered in terms of a simplified static 2D spin-pseudospin model. This model is equivalent to the…
Features of the Domain Boundaries of a Highly Anisotropic (S = 1) Antiferromagnet near the Transition to the Quantum Paramagnet Phase
V. V. Konev, V. A. Ulitko, D. N. Yasinskaya +2
It is shown that the structure of antiphase domain boundaries in the antiferromagnetic (AFM) phase of a highly anisotropic magnet with S = 1 on a two-dimensional square lattice dep…
