Determination of paramagnetic and ferromagnetic phases of an Ising model on a third-order Cayley tree [PDF]
Condensed Matter Physics, 2021 In this present paper, the recurrence equations of an Ising model with three coupling constants on a third-order Cayley tree are obtained. Paramagnetic and ferromagnetic phases associated with the Ising model are characterized.

Super-resolving the Ising model with convolutional neural networks [PDF]
Physical review B, 2018 Machine learning is becoming widely used in condensed matter physics. Inspired by the concept of image super-resolution, we propose a method to increase the size of lattice spin configurations using deep convolutional neural networks.

Multiplicity of periodic solutions in bistable equations [PDF]
, 2006 We study the number of periodic solutions in two first-order non-autonomous differential equations, both of which have been used to describe, among other things, the mean magnetization of an Ising magnet in a time-varying external magnetic field.

The Ising model celebrates a century of interdisciplinary contributions
npj ComplexityThe centennial of the Ising model marks a century of interdisciplinary contributions that extend well beyond ferromagnets, including the evolution of language, volatility in financial markets, mood swings, scientific collaboration, the persistence of ...

Topological dualities in the Ising model [PDF]
Geometry & Topology, 2018 Author(s): Freed, Daniel S; Teleman, Constantin | Abstract: We relate two classical dualities in low-dimensional quantum field theory: Kramers-Wannier duality of the Ising and related lattice models in $2$ dimensions, with electromagnetic duality for ...

Global quantum correlations in finite-size spin chains
New Journal of Physics, 2013 We perform an extensive study of the properties of global quantum correlations in finite-size one-dimensional quantum spin models at finite temperature. By adopting a recently proposed measure for global quantum correlations (Rulli and Sarandy 2011 Phys.

A Fully-Connected Ising Model Embedding Method and Its Evaluation for CMOS Annealing Machines
IEICE Trans. Inf. Syst., 2019 SUMMARY Combinatorial optimization problems with a large solu-tion space are di ffi cult to solve just using von Neumann computers. Ising machines or annealing machines have been developed to tackle these problems as a promising Non-von Neumann computer ...

Constrained percolation, Ising model, and XOR Ising model on planar lattices
Random Structures & Algorithms, 2020 We study site percolation models on planar lattices including the [m,4,n,4] lattice and the square tilings on the Euclidean plane () or the hyperbolic plane (), satisfying certain local constraints on degree‐4 faces. These models are closely related to Ising models and XOR Ising models (product of two i.i.d Ising models) on regular tilings of or .

Metastability for the Ising Model on the Hypercube [PDF]
Journal of Statistical Physics, 2017 We consider Glauber dynamics for the low-temperature, ferromagnetic Ising Model set on the n-dimensional hypercube. We derive precise asymptotic results for the crossover time (the time it takes for the dynamics to go from the configuration with a "-1" at every vertex, to the configuration with a "+1" at each vertex) in the limit as the inverse ...

Ising’s Roots and the Transfer-Matrix Eigenvalues
EntropyToday, the Ising model is an archetype describing collective ordering processes. As such, it is widely known in physics and far beyond. Less known is the fact that the thesis defended by Ernst Ising 100 years ago (in 1924) contained not only the solution
