Ising spin ladder with trimer rungs and next-nearest-neighbor coupling. Frustration in physics and agent models
Jozef Sznajd
The extended model of two-leg Ising spin ladder with trimer rungs and next nearest neighbor interaction (NNN) in an external magnetic field is studied using the transfer matrix and…
From modeling of political opinion formation to two-spin statistical physics model
Józef Sznajd
A two-spin system based on the idea used to formulate the dynamical model simulating the process of opinion spreading in a society, where people adopt one of the four social attitu…
Linear perturbation renormalization group method for Ising-like spin systems
J. Sznajd
The linear perturbation group transformation (LPRG) is used to study the thermodynamics of the axial next-nearest-neighbor Ising model with four spin interactions (extended ANNNI)…
Isothermal magnetocaloric effect in the vicinity of the Lifshitz point in Mn_{0.9}Co_{0.1}P
Tomasz Plackowski, Marcin Matusiak, Jozef Sznajd
The magnetic field - temperature (B - T) phase diagram of the Mn0.9Co0.1P single crystal is studied in the vicinity of the Lifshitz point by means of isothermal magnetocaloric coef…
Opinion evolution in closed community
Katarzyna Sznajd-Weron, Jozef Sznajd
A simple Ising spin model which can describe a mechanism of making a decision in a closed community is proposed. It is shown via standard Monte Carlo simulations that very simple r…
