Quantum physics: Atomic gas in flatland
Tilman Esslinger1 & Gianni Blatter1
Abstract
The observation of Bose–Einstein condensation in an atomic gas was a seminal result. Two-dimensional gases are more complex, and an intriguing interference experiment has exposed a different superfluid transition.
Atomic quantum gases are unique systems for investigating elementary concepts in many-particle physics. The most prominent example is Bose–Einstein condensation — the formation of a gaseous superfluid through the collapse of an ensemble of atoms into a single quantum state — which was first observed in an ultracold gas of rubidium atoms1.
- Tilman Esslinger and Gianni Blatter are in the Department of Physics, ETH-Zurich, CH-8093 Zurich, Switzerland.
