* Cold: Quantum degenerate, strongly interacting Fermi gases, were first produced in 2002; They can be efficiently produced by evaporative cooling in an optical trap and are now widely studied; They provide model systems for tabletop studies of high-temperature superconductivity, neutron stars, and nuclear matter.

* Nearly ideal gases: Their equations of state can be written down as series expansion in some parameter characterizing their deviation from ideal-gas behavior; For example, the Mayer Series Expansion and the Virial Expansion.
* Lorentz gas: A system of fixed dispersing scatterers, with a single light particle moving among these and making specular collisions on encounters with the scatterers; It can be taken to model a completely ionized gas, in which ions are assumed to be stationary and interactions between electrons are neglected.
* Granular gases: The main characteristic of a granular gas, which makes it fundamentally different from ordinary molecular gases, is its tendency to form clusters, i.e., to spontaneously separate into dense and dilute regions.
