Cold Gases


simulation of interference between atomic clouds

At room temperatures the behavior of a gas of atoms is dominated by their random thermal motion. Averaged over time this gives simple descriptions in terms of thermodynamic variables such as Temperature and Pressure. As the temperature is lowered, this thermal motion is reduced. The Heisenberg uncertainty principle prevents the atoms from coming to a stop. Instead, at nanokelvin temperatures, quantum mechanics dictates the properties of these atomic gases. We study this strange and beautiful form of quantum matter.

For some of our underlying motivations, please see essays written by individual group members:

Basic Physics of Cold Gases

It seems silly to write too much here. Instead we recommend that you look at some of the wonderful (interactive) essays on the subject which are already on the web:


These are a bit more technical, but are very useful.
