Ising model of Ferromagnets

The Ising model is one of the easiest and most famous theoretical models for ferromagnetism in statistical mechanics. When a group of atomic spins aligns such that their magnetic moments are pointed in the same direction and produce a strong permanent magnetic moment in macroscopic size, the phenomenon is called ferromagnetism. The relative permeability of these magnets is greater than unity and increasing magnetization with the applied external field. Even in the absence of an external magnetic field, these substances retain spontaneous magnetization. An example of ferromagnets is iron.

What are the rules for Gaussian elimination?
Parallel conducting plates create nearly uniform fields that are used to accelerate and direct beams of electrons. Typically we would free the electrons from a surface by heating it up. One way is to run a current through a wire with resistance. The power dissipated in the wire causes it to increase its temperature to the point that it can radiate that power away, mostly carried off as light. The hot electrons escape the potential barrier at the surface and are "free" to use. Consider a source of electrons that is small, like a tiny hot filament. The electrons are freed from the surface but the positive charge they leave behind holds them in a cloud near the filament. Now we add another plate at voltage VV some distance dd away. We put a little hole in that plate to enable the electrons to zip on through. The experiment looks something like this. While they seem antiquated, the concept is still useful. It is the basis of modern X-ray tubes, and until only a few years ago all…
