Digital micro-mirror devices make it possible to produce nearly arbitrary light fields. However, using these devices to trap ultracold atomic systems is often complicated by the presence of kHz-frequency switching noise. Here we demonstrate a simple hardware extension that solves this problem.

Observing the Influence of Reduced Dimensionality on Fermionic Superfluids

Understanding the origins of unconventional superconductivity has been a major focus of condensed matter physics for many decades. While many questions remain unanswered, experiments have found that the systems with the highest critical temperatures tend to be layered materials where...

Excitation Spectrum and Superfluid Gap of an Ultracold Fermi Gas

Ultracold atomic gases are a powerful tool to experimentally study strongly correlated quantum many-body systems. In particular, ultracold Fermi gases with tunable interactions have allowed to realize the famous BEC-BCS crossover from a Bose-Einstein condensate (BEC) of molecules to a...
