Exact solution for one-dimensional spin models with Markov property
Yu. D. Panov
For one-dimensional spin and pseudospin models that allow mapping to a Markov chain, the free energy of the system at a finite temperature can be expressed in terms of bond concent…

Pseudotransitions in a dilute Ising chain
Darya Yasinskaya, Yury Panov
This study provides a comprehensive analysis of the ground state and thermodynamic properties of a spin-pseudospin chain representing a model of a one-dimensional dilute magnet wit…

Correlation functions and properties of local distributions of frustrated phases in the ground state of a dilute Ising chain in a magnetic field
Yury Panov
The features of the response of frustrated states to the external field are considered on the example of a diluted Ising chain. In the ferromagnetic case, partial ordering occurs,…
