Experiments with ultra-cold Fermi gases
Slides - Day 3 (PPT, 11.70 MB) AbstractWhen thinking about Fermi gases, the first examples that probably spring to mind are neutron stars or the behaviour of electrons in metals. Very recently, it has become possible to create quantum degenerate Fermi gases from dilute vapours of fermionic atoms. Soon it became apparent that these clouds of atoms at a millionth degree above absolute zero provide ideal possibilities to create and study novel states of matter. Being a little bit more challenging to create than their siblings, the Bose-Einstein condensates, the effort proved to be worth while. They now represent a laboratory system with a unique amount of tunability, basically matter with “knobs on”. For example, it has been possible to observe superfluidity in such a gas while changing its properties continually from a fermionic nature into a Bose gas of tightly bound pairs of Fermions. In the future, it is expected that research on such ultracold Fermi gases will be able to shed new light into long-standing problems of quantum many-body physics, such as high temperature superconductivity. In this course we aim to give an introductory overview of this exciting and young research field. The following topics will be covered: The only prerequisite for this course is a good knowledge of quantum mechanics.
