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.

(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 ...

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.

Inference in Ising models

Bernoulli, 2018
The Ising spin glass is a one-parameter exponential family model for binary data with quadratic sufficient statistic. In this paper, we show that given a single realization from this model, the maximum pseudolikelihood estimate (MPLE) of the natural parameter is $\sqrt {a_N}$-consistent at a point whenever the log-partition function has order $a_N$ in ...

Macroscopically frustrated Ising model [PDF]

Physical Review E, 2001
A disordered spin glass model where both static and dynamical properties depend on macroscopic magnetizations is presented. These magnetizations interact via random couplings and, therefore, the typical quenched realization of the system exhibit a macroscopic frustration.

Ordering in Two-Dimensional Ising Models with Competing Interactions [PDF]

, 2005
We study the 2D Ising model on a square lattice with additional non-equal diagonal next-nearest neighbor interactions. The cases of classical and quantum (transverse) models are considered.

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 ...

Non-local order parameter for topological phase transition in the quantum toric code [PDF]

Iranian Journal of Physics Research, 2020
It has been known that by encoding the  Boltzmann weights of a classical Ising model in the amplitudes of the wave function of the ground state of the toric code model, the classical phase transition in Ising model is mapped to a topological phase ...
