Fisher zeros in the Kallen-Lehmann approach to 3D Ising model
(Elsevier Science, 2009-01)
The distribution of the Fisher zeros in the Kallen-Lehmann approach to three-dimensional Ising model is studied. It is argued that the presence of a non-trivial angle (a cusp) in the distribution of zeros in the complex ...
Detailed structure of configuration space and its importance on ergodic separation of ±J Ising lattices
(Elsevier Science, 2002-07-15)
A complete and exact characterization of the configuration space of 2-D ±J Ising lattices is performed. A new algorithm is introduced here representing advantages for reaching all states for small samples and doing a ...
Droplets pinned at chemically inhomogenous substrates: A simulation study of the two-dimensional Ising case
(American Physical Society, 2016-05)
As a simplified model of a liquid nanostripe adsorbed on a chemically structured substrate surface, a two-dimensional Ising system with two boundaries at which surface fields act is studied. At the upper boundary, the ...
Turing Instability in a Model with Two Interacting Ising Lines: Non-equilibrium Fluctuations
(Springer, 2019-01)
This is the second of two articles on the study of a particle system model that exhibits a Turing instability type effect. About the hydrodynamic equations obtained in Capanna and Soprano (Markov Proc Relat Fields ...
Phase Transitions and Multicritical Behavior of the Ising Model with Dipolar Interactions
(American Physical Society, 2016-10)
In this work, the phase diagram of the ferromagnetic Ising model with dipole interactions is revisited with the aim of determining the nature of the phase transition between stripe-ordered phases with width n (hn) and ...
Evidence of Kosterlitz-Thouless phase transitions in the Ising model with dipolar interactions
(American Physical Society, 2019-08)
The ferromagnetic bidimensional Ising model with dipolar interactions has been proposed to model ultrathin films with strong out-of-plane anisotropy. The phase diagram presents a rich phenomenology that includes lowtemperature ...
Effect of the ground-state structure on order parameters in ±J Ising lattices
(Elsevier Science, 2004-05)
The Edwards-Anderson site order parameter, q, or its generalizations have been considered to study the partial spin-glass behavior of ±J Ising lattices. These parameters vanish if all 2W ground states are taken into account, ...
Thermodynamic integration method applied to ±j Ising lattices
(Elsevier Science, 2005-03-15)
Square lattices with Ising spins at the sites and ±J exchange interactions between nearest neighbors are one of the realizations of the Edwards-Anderson model originally proposed to mimic spin glasses. Such systems produce ...
Phase transitions, order by disorder, and finite entropy in the Ising antiferromagnetic bilayer honeycomb lattice
(American Physical Society, 2018-07-30)
We present an analytical and numerical study of the Ising model on a bilayer honeycomb lattice including interlayer frustration and coupling with an external magnetic field. First, we discuss the exact T=0 phase diagram, ...
Phase transitions and critical phenomena in the two-dimensional Ising model with dipole interactions: A short-time dynamics study
(American Physical Society, 2015-09)
The ferromagnetic Ising model with antiferromagnetic dipole interactions is investigated by means of Monte Carlo simulations, focusing on the characterization of the phase transitions between the tetragonal liquid and ...
