Nonreciprocal Ising Model [PDF]
Physical Review Letters, 2023 Systems with nonreciprocal interactions generically display time-dependent states. These are routinely observed in finite systems, from neuroscience to active matter, in which globally ordered oscillations exist. However, the stability of these uniform nonreciprocal phases in noisy spatially-extended systems, their fate in the thermodynamic limit, and ...

Quantum phase transition dynamics in the two-dimensional transverse-field Ising model. [PDF]
Sci Adv, 2022 The quantum Kibble-Zurek mechanism (QKZM) predicts universal dynamical behavior near the quantum phase transitions (QPTs). It is now well understood for the one-dimensional quantum matter.

A Higher-Order Ising Model with Gradient-Free Update [PDF]
AxiomsThe Ising model is able to memorize some patterns or solutions as stable states. An Ising network may automatically converge to a pre-stored solution for a random input. However, in many cases, the Ising model cannot perform this task.

Computational complexity of spin-glass three-dimensional (3D) Ising model [PDF]
Journal of Materials Science and Technology, 2020 In this work, the computational complexity of a spin-glass three-dimensional (3D) Ising model (for the lattice size N = lmn, where l, m, n are the numbers of lattice points along three crystallographic directions) is studied.

A sparse ising model with covariates [PDF]
Biometrics, 2014 SummaryThere has been a lot of work fitting Ising models to multivariate binary data in order to understand the conditional dependency relationships between the variables. However, additional covariates are frequently recorded together with the binary data, and may influence the dependence relationships.

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 ...

The Fate of Ernst Ising and the Fate of his Model [PDF]
, 2017 On this, the occasion of the 20th anniversary of the “Ising Lectures” in Lviv (Ukraine), we give some personal reflections about the famous model that was suggested by Wilhelm Lenz for ferromagnetism in 1920 and solved in one dimension by his PhD student,

Majorana chain and Ising model - (non-invertible) translations, anomalies, and emanant symmetries [PDF]
SciPost Physics, 2023 We study the symmetries of closed Majorana chains in 1+1d, including the translation, fermion parity, spatial parity, and time-reversal symmetries. The algebra of the symmetry operators is realized projectively on the Hilbert space, signaling anomalies ...

Dynamical Process of a Bit-Width Reduced Ising Model With Simulated Annealing
IEEE Access, 2023 Ising machines have attracted attention as efficient solvers for combinatorial optimization problems, which are formulated as ground-state (lowest-energy) search problems of the Ising model. Due to the limited bit-width of coefficients on Ising machines,
