Effect of platy- and leptokurtic distributions in the random-field Ising model: Mean field approach
Silvio M. Duarte Queiros, Nuno Crokidakis, Diogo O. Soares-Pinto
The influence of the tail features of the local magnetic field probability density function (PDF) on the ferromagnetic Ising model is studied in the limit of infinite range interac…
First-order phase transition in a 2D random-field Ising model with conflicting dynamics
N. Crokidakis
The effects of locally random magnetic fields are considered in a nonequilibrium Ising model defined on a square lattice with nearest-neighbors interactions. In order to generate t…
Multicritical Behavior in a Random-Field Ising Model under a Continuous-Field Probability Distribution
Octavio R. Salmon, Nuno Crokidakis, Fernando D. Nobre
A random-field Ising model that is capable of exhibiting a rich variety of multicritical phenomena, as well as a smearing of such behavior, is investigated. The model consists of a…
Ising spin glass under continuous-distribution random magnetic fields: Tricritical points and instability lines
N. Crokidakis, F. D. Nobre
The effects of random magnetic fields are considered in an Ising spin-glass model defined in the limit of infinite-range interactions. The probability distribution for the random m…
Destruction of first-order phase transition in a random-field Ising model
N. Crokidakis, F. D. Nobre
The phase transitions that occur in an infinite-range-interaction Ising ferromagnet in the presence of a double-Gaussian random magnetic field are analyzed. Such random fields are…
