Clifford algebra approach of 3D Ising model [PDF]
Advances in Applied Clifford Algebras, 2018 We develop a Clifford algebra approach for 3D Ising model. We first note the main difficulties of the problem for solving exactly the model and then emphasize two important principles (i.e., Symmetry Principle and Largest Eigenvalue Principle) that will ...

Parallel simulation of the Ising model [PDF]
Physical Review E, 1994 Methods for parallelizing Ising model simulations are presented. A parallel single-spin Metropolis algorithm [J. Chem. Phys. 21, 1087 (1953)] has been implemented with a speedup of 27 on 50 processors of the KSR-1 parallel computer. A parallel Swendsen-Wang algorithm [Phys. Rev. Lett.

Imaginary multiplicative chaos: Moments, regularity and connections to the Ising model [PDF]
The Annals of Applied Probability, 2018 In this article we study imaginary Gaussian multiplicative chaos -- namely a family of random generalized functions which can formally be written as $e^{i X(x)}$, where $X$ is a log-correlated real-valued Gaussian field on $\mathbb{R}^d$, i.e.

Ising model and the positive orthogonal Grassmannian [PDF]
Duke mathematical journal, 2018 We completely describe by inequalities the set of boundary correlation matrices of planar Ising networks embedded in a disk. Specifically, we build on a recent result of M.~Lis to give a simple bijection between such correlation matrices and points in ...

Spin-Flip Dynamics of the Curie-Weiss Model: Loss of Gibbsianness with Possibly Broken Symmetry [PDF]
, 2007 We study the conditional probabilities of the Curie-Weiss Ising model in vanishing external field under a symmetric independent stochastic spin-flip dynamics and discuss their set of points of discontinuity (bad points). We exhibit a complete analysis of

Sampling of thermodynamic systems with neural network surrogates
UMYU Scientifica Journal, 2022 Traditional sampling methods such as the Monte Carlo method are computationally expensive and not feasible for studying large and complex systems. These methods are essential for developing new materials, optimizing chemical reactions, and understanding ...

The two-dimensional Ising model
From Quarks to Pions, 2018 In this thesis the equivalence of the two-dimensional critical classical Ising model in the scaling limit without a magnetic field, the (one-dimensional) critical quantum Ising chain in the scaling limit, the free fermion with a Dirac mass term, theM(3 ...

Bootstrapping the long-range Ising model in three dimensions [PDF]
Journal of Physics A: Mathematical and Theoretical, 2018 The 3D Ising model and the generalized free scalar of dimension at least 0.75 belong to a continuous line of nonlocal fixed points, each referred to as a long-range Ising model.

Computing the Cramer-Rao bound of Markov random field parameters: Application to the Ising and the Potts models [PDF]
, 2013 This letter considers the problem of computing the Cramer–Rao bound for the parameters of a Markov random field. Computation of the exact bound is not feasible for most fields of interest because their likelihoods are intractable and have intractable ...

Static universality of the Ising and Blume–Capel models on two-dimensional Penrose tiles
Results in Physics, 2023 We study the phase transitions and the critical behavior of the Ising and Blume–Capel models on two kinds of two-dimensional Penrose tiles employing Monte Carlo methods and detailed finite-size scaling analysis.
