Physical Review B, 1988
In this paper we describe a numerical method of solving the local-density mean-field equations of spatially frustrated lattice models. Using techniques of simulated annealing and simultaneous updating of collective modes, we have been able to locate the global minima of a function with many nearby local minima.

Kids love models, and on page 792 of this issue Shimizu et al. give us an early Christmas present. Using plastic replicas of the CheA, CheW, and Tsr protein structures, they assembled the pieces like a jigsaw puzzle.

Model World: A Model Is a Model Is a Model Is a Model
Interfaces, 1989This occasional column will address issues — both real and imaginary — that impinge on what I think is the main activity of management science/operations research: building models that attempt to describe the world as it was, as it is, and as it will be.

Advances in Applied Probability, 1978
Ising lattices model spatial interaction among binary variables, and consequently, are relevant to many scientific disciplines. They are intuitively appealing models because their conditional distributions are given locally (they are Markov fields). On the other hand, their marginal distributions (even for pairs of sites, let alone triples, etc.) are ...

Physical Review B, 1995
We consider the phase diagram of two randomly coupled Ising models to mimic the successive phase transitions in plastic crystals. Detailed mean-field calculations are performed. Depending on the strength of the couplings, the phase diagrams display three ordered phases and some multicritical points.

Inference: International Review of Science, 2018
In the last 75 years, physicists have solved the 2D Ising model of ferromagnetism in numerous ways. The solutions may be combinatorial, algebraic, or analytic—but all come to the same result.

A New Proof of the Sharpness of the Phase Transition for Bernoulli Percolation and the Ising Model
Communications in Mathematical Physics, 2015We provide a new proof of the sharpness of the phase transition for Bernoulli percolation and the Ising model. The proof applies to infinite-range models on arbitrary locally finite transitive infinite graphs.

Ising ferrimagnetic models. II
Journal of Physics C: Solid State Physics, 1974In the systems considered the lattice is divided into sub-lattices of Na and Nb sites occupied by spins of magnetic moment mu a and mu b respectively such that Na mu a not=Nb mu b. The exchange interactions tend to line up the a and b spins in opposite directions.
