Ultracold Quantum Gases
Prof. Dr. Leticia Tarruell
- Activities:
We use ultracold atomic gases as model systems to experimentally explore fundamental phenomena in quantum many-body physics. By exploiting atom-light interactions, we engineer highly controllable artificial quantum materials and probe their properties. Our goal is to employ these systems as quantum simulators for studying open problems in condensed-matter physics, and to realize novel phases without counterpart in the solid-state context. Our research therefore lies at the crossing between quantum optics and condensed-matter physics.
This group has opportunities for outstanding Masters students, PhD students and postdocs. For more information, please contact This email address is being protected from spambots.
