LKB - Ultracold Fermi Gases

ULTRACOLD FERMI GASES

Our group studies the physics of ultracold Fermi gases in a regime where the interplay between interactions and quantum statistics gives rise to strong correlations between particles. At low temperature, the collective behavior of these interacting particles leads to dramatic effects, such as superfluidity, the analog for neutral particles of superconductivity. While strongly correlated Fermi systems are ubiquitous in Nature and modern materials, they are notoriously difficult to tackle theoretically. Our experiments provide quantum simulators of generic or unconventional Hamiltonians where precision measurements of static and dynamic properties are accessible. The combination of our experimental and theoretical expertise aims at improving our understanding of strongly correlated quantum matter. This research lies at an interesting interface between atomic physics, condensed matter, and particle physics.

JOB OFFERS

2017 - Master's Projects

Our group advertises two openings for experimental Master’s projects in the field of ultracold Fermi gases staring spring 2017. We are seeking students interested in quantum mechanics, optics and laser physics. We offer the possibility to work on several projects on three different apparatus.

We encourage early applications in order to ensure lodging at ENS housing, which are within 15 minutes commuting time from the lab location.

These positions come with a monthly stipend that covers lodging at ENS housing and part of living expenses.

2017 - PhD

We have three openings for PhD positions on our quantum gas experiments, starting September 2017.
