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.

Revisiting the combinatorics of the 2D Ising model [PDF]
, 2017 We provide a concise exposition with original proofs of combinatorial formulas for the 2D Ising model partition function, multi-point fermionic observables, spin and energy density correlations, for general graphs and interaction constants, using the ...

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 ...

Ising model with stochastic resetting [PDF]
Physical Review Research, 2020 We study the stationary properties of the Ising model that, while evolving towards its equilibrium state at temperature $T$ according to the Glauber dynamics, is stochastically reset to its fixed initial configuration with magnetisation $m_0$ at a ...

Simulating the Shastry-Sutherland Ising Model Using Quantum Annealing [PDF]
PRX Quantum, 2020 Frustration represents an essential feature in the behavior of magnetic materials when constraints on the microscopic Hamiltonian cannot be satisfied simultaneously. This gives rise to exotic phases of matter including spin liquids, spin ices, and stripe

Entanglement transition in the projective transverse field Ising model [PDF]
, 2020 Discrete quantum trajectories of systems under random unitary gates and projective measurements have been shown to feature transitions in the entanglement scaling that are not encoded in the density matrix.

The Theoretical and Statistical Ising Model: A Practical Guide in R
Psych, 2021 The “Ising model” refers to both the statistical and the theoretical use of the same equation. In this article, we introduce both uses and contrast their differences.

Revising the universality class of the four-dimensional Ising model
Nuclear Physics B, 2023 The aim of this paper is to determine the behavior of the specific heat of the 4-dimensional Ising model in a region around the critical temperature, and via that determine if the Ising model and the ϕ4-model belong to the same universality class in ...

Guiding Principle for Minor-Embedding in Simulated-Annealing-Based Ising Machines
IEEE Access, 2020 We propose a novel type of minor-embedding (ME) in simulated-annealing-based Ising machines. The Ising machines can solve combinatorial optimization problems. Many combinatorial optimization problems are mapped to find the ground (lowest-energy) state of
