Bayesian computation for statistical models with intractable normalizing constants

Atchade, Yves; Lartillot, Nicolas; Robert, Christian P. - Université Paris-Dauphine (Paris IX) - 2012

This paper deals with some computational aspects in the Bayesian analysis of statistical models with intractable normalizing constants. In the presence of intractable normalizing constants in the likelihood function, traditional MCMC methods cannot be applied. We propose an approach to sample...

Dynamic phase transitions in the kinetic spin-1 Blume–Capel model on the Bethe lattice

Deviren, Seyma Akkaya; Albayrak, Erhan - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 20, pp. 3283-3289

The stationary states of the kinetic spin-1 Blume–Capel (BC) model on the Bethe lattice are analyzed in detail in terms of recursion relations. The model is described using a Glauber-type stochastic dynamics in the presence of a time-dependent oscillating external magnetic field (h) and...

Exact solution on the magnetism and ferroelectricity in the Ising spin chain

Qi, Yan; Du, An - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 6, pp. 1064-1071

In this paper, we explore the magnetoelectric coupling in Ca3CoMnO6-type compound with the consideration of interaction between spins. Under the linear approximation of nearest-neighbor spin interaction with respect to the ion displacement, both the Hamiltonian and the partition function of the...

As an example, we focus on the staggered spin-S Ising model in the presence of a longitudinal magnetic … field, comparing some of its thermodynamic functions to those of the standard Ising model. We show that for arbitrary values …-1/2 models in a suitable interval of temperature. These approximations are valid for the standard Ising model as well as …
