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 ...

Eigenstate thermalization in the two-dimensional transverse field Ising model. II. Off-diagonal matrix elements of observables. [PDF]
Physical Review E, 2017 We study the matrix elements of few-body observables, focusing on the off-diagonal ones, in the eigenstates of the two-dimensional transverse field Ising model.

Mathematical modeling of pandemic Covid-19 [PDF]
ریاضی و جامعه, 2022 In this paper, by introducing well-established epidemiological models, compartmental models and Ising models, examples of their applications in describing epidemics, including some aspects of Covid-19, and several perspectives are presented.

Quantum approximate optimization of the long-range Ising model with a trapped-ion quantum simulator
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance Variational quantum algorithms combine quantum resources with classical optimization methods, providing a promising approach to solve both quantum many-body and classical optimization problems.

Joint estimation of parameters in Ising model [PDF]
Annals of Statistics, 2018 We study joint estimation of the inverse temperature and magnetization parameters $(\beta,B)$ of an Ising model with a non-negative coupling matrix $A_n$ of size $n\times n$, given one sample from the Ising model.

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.

Toward a 3d Ising model with a weakly-coupled string theory dual
SciPost Physics, 2020 It has long been expected that the 3d Ising model can be thought of as a string theory, where one interprets the domain walls that separate up spins from down spins as two-dimensional string worldsheets.

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 ...
