A simple d -dimensional lattice model is proposed, incorporating some degree of frustration and thus capable of describing some aspects of molecular orientation in covalently bound molecular solids. For d = 2 the model is shown to be equivalent to the standard two-dimensional Ising model, while ...
Introduced in 1963, Glauber dynamics is one of the most practiced and extensively studied methods for sampling the Ising model on lattices. It is well known that at high temperatures, the time it takes this chain to mix in L^1 L^1 on a system of size n n is O(\log n) O(\log n...

Spontaneous magnetization of the three-spin Ising model on the Union Jack lattice The spontaneous magnetization of the Ising model with pure three-spin interactions on a Union Jack lattice is obtained in terms of the magnetic and the fer... FY Wu - 《Journal of Physics C Solid State Physics...
A two-dimensional lattice model has been developed to describe the influence of vegetation on the turbulent flow structure in an open channel. The model includes the influence of vegetation density on the frictional effect of the channel bed and walls. For the walls, a semi-slip boundary conditi...
A random-medium model which is a correlated distribution of points (particles) randomly positioned in the 3-dimensional space is considered. The construction of the medium starts from a noncorrelated (Poisson) distribution of parent particles, each of them initiates a finite Markov chain of its de...
Field behavior of an Ising model with competing interactions on the Bethe lattice. The Ising model on the Bethe lattice of general connectivity, with competing interactions between the first-, second-, and third-neighbor spin generations has been studied. In our approach the partition function, ...
The latter can be fitted with a lattice gas model calculation. Effort is made to understand why the model fails for Gold on Gold. The calculation suggests that the large Coulomb interaction which is operative for the larger system is responsible for this discrepancy. This is demonstrated by ...
The term mental model is widely used, and its meanings vary just as widely, from a proposed mechanism for logical deduction to an operator's memory of the structure of a complex industrial system. In this chapter, the relationships betwe... N Moray,D Gopher,A Koriat - 《Attention & Perf...
