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 ...

Particle-based Ising model [PDF]
Physical Review E, 2021 We characterize equilibrium properties and relaxation dynamics of a two-dimensional lattice containing, at each site, two particles connected by a double-well potential (dumbbell). Dumbbells are oriented in the orthogonal direction with respect to the lattice plane and interact with each other through a Lennard-Jones potential truncated at the nearest ...

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 ...

(Four) Dual Plaquette 3D Ising Models
Entropy, 2020 A characteristic feature of the 3 d plaquette Ising model is its planar subsystem symmetry. The quantum version of this model has been shown to be related via a duality to the X-Cube model, which has been paradigmatic in the new and rapidly ...

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.

Topological defects on the lattice: I. The Ising model [PDF]
, 2016 In this paper and its sequel, we construct topologically invariant defects in two-dimensional classical lattice models and quantum spin chains. We show how defect lines commute with the transfer matrix/Hamiltonian when they obey the defect commutation ...

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.

Petri Net Modeling for Ising Model Formulation in Quantum Annealing
Applied Sciences, 2021 Quantum annealing is an emerging new platform for combinatorial optimization, requiring an Ising model formulation for optimization problems. The formulation can be an essential obstacle to the permeation of this innovation into broad areas of everyday ...

Cell death and survival due to cytotoxic exposure modelled as a two-state Ising system [PDF]
Royal Society Open Science, 2020 Cancer chemotherapy agents are assessed for their therapeutic utility primarily by their ability to cause apoptosis of cancer cells and their potency is given by an IC50 value.

Interpreting the Ising Model: The Input Matters [PDF]
Multivariate Behavioral Research, 2018 The Ising model is a model for pairwise interactions between binary variables that has become popular in the psychological sciences. It has been first introduced as a theoretical model for the alignment between positive (1) and negative (−1) atom spins ...
