[edit] Simulation

It might be nice to have interactive billiard simulations. Anyone know how to do that? --MarSch 12:48, 20 October 2005 (UTC)

[edit] Lorenz gas?

Does this cover the same topic as Lorenz gas, or is that something different? (Lorentz gas redirects to this page.) Mike Peel 11:26, 11 October 2006 (UTC)

A Lorentz gas is a model for an electron moving through a lattice of atoms. Lorentz introduced this model in 1904 to study the heat and electrical conductivity of metals. Experimentally, Lorentz's model was not as good as Drude's model, but it provided the first example of a solution (although perturbative) to the transport equation when there are interactions. An often studied example of the Lorentz gas is a billiard, made famous by Sinai, where a fixed set of disks scatter a single point particle. The collisions are specular and the disks are usually arranged to form a periodic lattice. I am not aware of a Lorenz gas. XaosBits 13:53, 13 October 2006 (UTC)

[edit] Pump Field?

The addition of information about "pump fields" seems to dangle. the "pump" field is not defined anywhere else (and I assume means the fiber coupling source of energy). This should be stated explicitly (but I'm reluctant to do so since this is not my primary area). Nonetheless, I tried to fix up the language associated with that part of the article.
