The Curie–Weiss model is an exactly solvable model of ferromagnetism that allows one to study thermodynamic functions in detail, in particular their properties near the critical temperature. In this model every magnetic moment interacts with every other magnetic moment. Because of its simplicity and the correctness of at least some of its predictions, the Curie–Weiss model occupies an important place in the statistical mechanics literature and its application to information theory. It is… 
Spontaneous magnetization of ferromagnet in mean-field Heisenberg model
The Heisenberg ferromagnet model has been studied theoretically using the Weiss mean-field theory and Green’s function technique. The equations for the Curie temperature, magnetization, and magnetic

TLDR
The Landau theory of phase transitions has been re-examined under the framework of a modified mean field theory in ferroelectrics and it turns out that it is the behavior of the nematic phase on approaching the critical point that makes the Landau Theory deviate from experimental observations.
Order Parameter in Short-Range and Long-Range Ising Finite Feromagnetic Models
The approach to determination of the order parameter in the finite 1D Ising model was proposed. For such systems a root mean square magnetization and an average size of the maximal ground state
Exact and approximate analytical solutions of Weiss equation of ferromagnetism and their experimental relevance
The recent progress in the theory of generalised Lambert functions makes possible to solve exactly the Weiss equation of ferromagnetism. However, this solution is quite inconvenient for practical
Analytic solutions of the modified Langevin equation in a mean-field model
Approximate analytical solutions of the modified Langevin equation are obtained. These solutions are relatively simple and enough accurate. They are illustrated by considering a mean-field model of a
Partition Function and Density of States in Models of a Finite Number of Ising Spins with Direct Exchange between the Minimum and Maximum Number of Nearest Neighbors
The results of studies of 1D Ising models and Curie-Weiss models partition functions structure are presented in this work. Exact calculation of the partition function using the authors combinatorial
Equivalence of ensembles in Curie-Weiss models using coupling techniques
We consider equivalence of ensembles for two mean field models: the discrete, standard Curie-Weiss model and its continuum version, also called the mean-field spherical model. These systems have two
Analytic solutions of the Weiss mean field equation
Abstract Analytic solutions of the Weiss mean field equation are obtained using an approximant of the inverse Langevin function. These solutions provide temperature dependencies of the magnetization
Polaron-transformed dissipative Lipkin-Meshkov-Glick model
We investigate the Lipkin-Meshkov-Glick model coupled to a thermal bath. Since the isolated model itself exhibits a quantum phase transition, we explore the critical signatures of the open system.
Dilution of Ferromagnets via a Random Graph-Based Strategy
TLDR
This work proposes a Monte Carlo method, based on random graphs, for modeling ferromagnets with dimension , which can be approximated by the Curie-Weiss model, and uses a modified version of the Erdős-Renyi graph model for this purpose.
