Welcome

In a famous paper, P. W. Anderson coined the phrase “more is different”, capturing the essence in many research fields in physics: A system of many constituents of the same nature (many electrons, atoms, etc) is not just “more of the same”; it is altogether a different system, with strikingly different physical phenomena. In order to understand the behavior of a complex system (from electrons in metals, to a pile of rice), it is not enough to know the basic laws of physics. It is necessary to  develop new theoretical framework and base it on extensive experimental data.

A very important class of complex systems is that of interacting fermions. Examples include electrons in metals, a liquid of  3He, neutrons in a neutron star, and more. We are studying the many-body physics of strongly interacting Fermions using an ultracold gas of potassium 40. Using lasers and magnetic fields, we trap and cool down the atoms in a vacuum chamber. We can alter their interaction with each other, their geometrical configuration, temperature, and many other parameters. When the atoms reach low enough temperature, they form a fermionic superfluid. We can observe and study this fascinating physics directly with a CCD camera.
